We love the staff who went out of their way to make our stay special. Of particular note were Eva and Sophia from the front desk, Thanos and Chris from the meals. And finally, our spa therapist Maria. The spa is something special, with views that are simply breathtaking. The food is excellent and among the best we ate on the island which itself is known for food.

The gym is beautifully built and is open air. It gets too much sun in the morning making a workout at that time pretty hard.

The setting was really lovely and the pool area was very comfortable - there isn't a lot of shade but you do get a lovely breeze. There is a cute outdoor gym but not much shade so it gets too hot very early in the day. Our room was really lovely - great Acqua di Parma amenities, super comfortable bed and a wonderful terrace with a plunge pool and relaxation area overlooking the sea.

The breakfast could be improved - in the cold selection, it was mainly many cakes - we would have preferred more fresh fruit, cheeses etc. The cooked breakfast wasn't very tasty. There weren't any spare plug sockets for personal items and the side tables were taken up by a big lamp which meant no space to place water/possessions by the bed. There was a Marshalls radio but again, this couldn't be plugged in or placed anywhere. It might have been nice to have a little armchair with a side table a plug socket in the room as there was plenty of space for it. The water in the shower didn't get too hot but understand it's an island.

The design of the hotel is beautiful, very comfortable rooms and beds, very quiet.

Considering the price (1200euros) I was a bit disappointed by the size of the room and bathroom. If you have a big suitcase there is no room to store it . They would be also need to have more place in the shadow, for breakfast, to relax etc

Nos = BLISS! It was our first vacation in four years and we decided to splurge. NOS is so tranquil, so quietly gorgeous, and so relaxing that we made up for lost time. The staff is always helpful and knowledgeable and kind (shout out to Maria and to the amazing, hard-working and generous wait staff) and the food is SOOOO good. Breakfast buffet every morning along with delicious home-cooked egg dishes, great coffee, and wonderful views no matter where you sit. At least one dinner at the restaurant is a must-do. We loved the ceviche, Greek salad, and the lemony chicken. And it is impossible to have a bad glass of wine there. From the resort we took many walks and hikes into the wild and beautiful countryside. Sifnos is best enjoyed with hiking boots and a good appetite. Beware, though. Greece has gotten expensive. Save up your euros, because it's worth it.

Not a thing. Nos was heaven.

In properties like this it is difficult to find something that it’s wrong! You are usually thinking about what could have been done better. Absolutely amazing experience, service and greek hospitality at its best.

Mattress was on the soft side something which i am not very keen for. Again this is a matter of personal preference but i do think that something more neutral is better for majority of people regardless their body types.

Endless views! Everywhere you look, a stretch of blue. Nos is an exceptional property in an exceptional location. This is the hotel to book if you want to completely relax, unwind and feel at peace with the world. Staff are professional, discrete and highly competent, from reception to poolside and restaurant, which serves delicious fare at equally fair prices. Breakfast is varied, generous, includes authentic Sifniote foods and is once again served with a view. An enormous amount of thought was obviously put into the design of this property. It is by far the most exceptional hotel we have ever stayed in.

The pillows.

This hotel is absolutely incredible. It looks better in person than the pictures. Alexandra and her team are all extremely friendly and super helpful. The pool, spa, food, cocktails, rooms, everything are all perfect. Beaches and lovely restaurants walking distance. Would 100% stay here again.

Plentiful breakfast spread, very nice pool, and attractive, modern decor. Nice lunch menu.

There were not enough lounge chairs at the pool and no shade when it was too windy to use the umbrellas (which is often). The towels covering the lounge chairs were not changed between guests and it appeared they were left on for days. The dinner menu was too limited and expensive. We were disappointed to discover - without notice - that the "all day" menu was only available until 7:30pm.

All. Views. Location. All the personnel Girls at reception were great always trying to satisfy all needs. Maria from the spa a must !!! Harry the chofer excellent. All 10 points Will come back for sure

the building design and fabulous staff

the food was of the highest quality but the outdoor restaurant was a bit windy and there is no alternative . I think they need a protected dining area as this island is known as being windy . we ate there for 2 nights but for the other 3 nights we went out of the hotel to more sheltered settings in other restaurants … but the food was fabulous and I do get what they were trying to acheive …
