Onyx is as close to flawless as I have experienced! The rooms are beautiful - we stayed in a junior suite with plenty of room for 2 adults and 2 teenagers for 2 days. The decor is beautiful and the place is spotlessly clean. The staff are AMAZING. So helpful and so friendly. Thanks to Konstantina and Tamta for being so helpful. Poolside bar is lovely and breakfast there is lovely - there’s plenty to choose from. Perhaps in time they might be able to offer a sandwich or salad at lunchtime - in the absence of that, we got gorgeous toasted sandwiches in a new cafe around the corner and ate them on our terrace. Location is lovely - It’s about a 20 minute walk to Fira town centre or €25 in a taxi. You could taxi in and walk home as it’s downhill! I would go back in a heartbeat.

The hotel was gorgeous and finished to such a high spec I was amazed we got it for the price we did. The staff are what really made the stay a 10/10 both Denisa and Victoria went above and beyond to make our stay the best. I wished we had stayed longer! We told them our time limit and budget and they recommend several things we could do in that time, we managed to do them all and under budget. I even had a query about stamps and postcards which they not only answered, but solved by obtaining the stamps and posting them for me. Honestly, greek hospitality is something else. This will be a repeat booking for me for years to come, I can't recommend it enough.

We only stayed one night, I wish we had booked longer!

The staff were amazing! Especially Denisa and Maria, our receptionists. They were smiling, welcoming and considerate. (Our experience in Athens was not like this) We arrived knowing not much about Santorini and they gave us a pro recommendation for all the things we can do here. They can also rent cars(at a cheaper price than airport) and book cruise for you. They prepared a surprise honeymoon cake I asked for which was absolutely delicious and pretty. They even gifted us a bottle of Greek white wine and upgraded our room. Thanks! You can feel they had a good training and their goal is to make you feel at home and enjoy your holiday with no worries. A good service is why onyx have a good review and stand out from surrounding fierce competition. As for the hotel itself. It is in the middle of the island, close to Fira and 20 mins drive to Oia. The room was cleaned everyday, bed was comfortable. Many choices for breakfast. Pool was pretty with progressing depth.

The breakfast coffee choice is limited, I guess it’s made from powder with water. We had to pay extra to have a cappuccino which is more expensive than a bar within walking distance. Would be nice if they provide a coffee machine or make coffee for guests. After all we paid for our breakfast.

The hotel staff and amenities were amazing. The hotel staff was very friendly and always tried to ensure we had everything we needed. The breakfast service was absolutely amazing, the gentleman always gave us ideas where to go and was pleasure to chat with. The bar service was great, we had some amazing cocktails while laying at the comfortable beach chairs enjoying the sun. Cleaners ensure we always had clean towels and our room looked spotless.

The hotel is located in the quiet area of ​​Karterados, 5 minutes by car from Fira. Maria at the reception, welcomed us with a smile and gave us information about restaurants and activities. She also made us a reservation at a great restaurant in Pyrgos and arranged for us to have perhaps the best table to watch the sunset. Denisa, the other girl at the reception, also very, very helpful ❤️ The room was spacious enough for 4 people and spotlessly clean. The pool area was clean and quiet, ideal for relaxing. The pool is open until eight so you can see the sunset as you swim. Litsa at the bar is a bonus for the hotel. Always cheerful and willing to help. Litsa, we missed the margaritas :) If you rent a car, there is a comfortable parking space right outside the hotel. You made our stay in santorini even more magical and wonderful ❤️

Very nice hotel! We were met by Maria at the reception desk who went over and above to explain about the hotel, amenities, and things to see and do on Santorini. She even helped us book an afternoon catamaran cruise for the next day :) Our room was very spacious, with a large separate sitting area - way bigger than expected! Great pool area with lounge chairs, and bar with both drinks and light snack food options. Excellent breakfast! Very good location - only a couple of minutes from Fira.

Only minor negative point was the rain shower head in our room was clogged quite badly - it likely needed a good decalcification. Other than that, we hated that we'd only booked for 3 nights ;)

We have just returned from Santorini and stayed at Onyx during our stay on the island. The location is perfect if you want some some tranquility away from the crowds in Thira, but equally a close distance when you do want to dip in. As its central on the island, the north and south of the island are in easy reach, especially if hiring a car or quad. Katia, Denisa, Litsa and all of the other staff gave us a typically Greek welcome with their friendliness, and they went above and beyond to make our stay special, from arranging airport transfers, restaurant recommendations and reservations to car hire. We couldn’t have asked any more of them and they were all fabulous! The rooms are very clean, and high standard with a greek contemporary vibe, the pool area is just as lovely! Breakfast was simple continental, with a small hot food offering (eggs & bacon/sausage), but the food was lovely and enough to start our day. The Greek salad we ordered at lunch time from the pool bar was everything we love about Greek food. We had an amazing stay and would absolutely return and recommend in a heartbeat!

My only constructive feedback is that the drink prices at the pool bar are on par with the caldera view bars/restaurants and could be cheaper for residents (we’d have definitely spent more at the bar rather than at the local shop if this was the case).

This hotel is amazing. The rooms are new, modern and comfortable. The staff cleaned the room every day. The breakfast is very good; you can choose between different fresh ingredients (eggs, fruit, Greek yogurt, Greek salad, different pastries, bread, juice and coffee). The pool is very nice and clean. You can get fresh pool towels everyday and also some snacks and cocktails (very good, by the way). The music by the pool is nice and relaxing. But the best thing about this hotel is the staff. Maria (and also all the others) are absolutely amazing; she was very kind, always smiling and always willing to help. We were on our honeymoon, and they upgraded our room to one with the jacuzzi for free. She gave us great recommendations for restaurants and activities; she helped us rent an ATV; she arranged for a taxi...Also, the location is very convenient (20 min to Oia, 10 min to Kamari, 15 min to Imerovigli and 10 min do Fira). The bus station is 10 min away by foot, and there are also good restaurants and mini markets nearby. Amazing & worth the price!!

everything was perfect

Never have we experienced such an incredible time as we did while staying at the Onyx Hotel & Suites. From start to finish, our stay was nothing short of extraordinary. The pool area was immaculate, with an abundance of comfortable loungers and attentive staff who were always ready to bring refreshments with a smile. It was the perfect place to relax and unwind, and we couldn't have asked for a better atmosphere. Maria and Denisa are, without a doubt, the best hostesses we have ever encountered. Their warmth, professionalism, and attention to detail made us feel truly special throughout our stay. Combined with the rest of the exceptional staff and the luxurious facilities, our time at Onyx stands out as one of the best hotel experiences of our lives. The team's dedication to quality, comfort, and the finer details made every moment memorable. Staying here was worth every penny, and we cannot recommend the Onyx Hotel & Suites highly enough. Thank you once again, Maria, Denisa, and the entire Onyx team, for everything you've done for us. We can't wait to return. Camilla & Rasmus

Maria was a lovely welcome host and so knowledgable about all of the best places to visit on the island. The hotel was beautiful and in a good location, only about a 10 minute ATV ride down to Fira town. The room was clean, all of the staff were friendly and the general atmosphere was welcoming. The bed was the best we stayed in, during our whole 12 day trip to Greece! Our flight home was in the evening on the last day, and the staff let us stay by the pool until it was time to go. We would definitely come again!

It would have been nice to have more variety of snacks at the pool bar, but even so, what was offered was delicious!
