The hotel is absolutely lovely! The rooms are spacious, comfortable, and exceptionally clean. The kitchen is fully equipped with high-quality, spotless appliances. Every single staff member was cheerful, always smiling, and made us feel genuinely welcome. The free parking is very close to the hotel and there were always free spots available. The location is excellent — right on the main road and easy to reach. There are restaurants and cafés right next to the hotel, and a large shopping mall is just a short walking distance away. We will definitely return to this hotel every time we visit Ljubljana!

I didn't plan to book this hotel but when I saw the review score (9.3) I decided to give it a try. The hotel is new (maybe 2 years old, not more), rooms are spacious and warm, bathroom is huge and clean, ... I had interaction with 4 staff members (3 from the reception and 1 housekeeper) - Housekeeping service is PERFECT! The rooms was cleaned every day, towels were changed every day even if I didn't need them to be changed but they did it :) . There are many food options nearby. The hotel offers also meals from the nearby delivery restaurant - very good food! Usually when I see so high review score I check for how much reviews in total they have (because I always think it's a fraud) - believe me, this hotel is really PERFECT as you can see from the review score! Hotel staff - keep up the good work!

Since they have so high review score I think they should start with some extra hospitality training with their staff (ex. to ask guest how they feel, to ask them how was their stay, etc...). They have TOP product and as I can see very good staff, now they should just upgrade that to the next level to achieve even higher review score from the current (9.3).

I had 3 rooms reserved. Before the trip, a friend of mine called to say that he wouldn't be able to go. When we arrived at the hotel, I asked if we could cancel one room we will not use. The guy at the reception personally made the effort to call the Booking Customer Service department and cancel that room for us, so I only paid for the two we used. The rooms are good and the breakfast was excellent. When I come to Ljubljana again, we will definitely come back here.

We didn't have any bad experience.

I was very happy with my stay at ONE66. The room was very small but smartly partinioned and comfortable. I was initially set aback because it was in the basement, but the small windows were big enough for fresh air. The location of the hotel turned out to be great, despite some distance to the city center. With the many bus routes passing by, you can get basically anywhere in the city and you just pay 1,30€ per ride with a credit card. Within five minutes walking distance, there are several restaurants, supermarkets and even a big shopping center. One of the main reasons why I picked this hotel was the fact that they have a gym, and I was thrilled with the equipment. Aside from the typical cardio machines and medicine balls, they have a rowing machine, several cable machines, a smith machine, two benches with dumbbells up to 26kg (57kbs) and a combination leg curl / extention machine. The breakfast was basic, and I would have liked more vegan options, like a spread for the bread, for example. I did not eat or drink anything else. The staff was very friendly and helpful. The interior design is, as always, a matter of taste, but it is obvious that somebody put a lot of thought into the hotel. I will surely stay here again when I visit the beautiful city of Ljubljana in the future!

Our stay at this hotel was absolutely wonderful and exceeded all our expectations. From the moment we arrived, the staff made us feel so welcome and cared for. The apartment was beautiful, spacious, and incredibly comfortable, the breakfast was delicious and thoughtfully prepared, and the entire atmosphere of the hotel felt calm, warm, and uplifting. At times we even joked that we could’ve spent the whole trip just enjoying the hotel and would’ve been just as happy! Thank you for creating such a unique and heartfelt place – it truly made our stay in Ljubljana unforgettable. 💛

The staff could not have been more helpful and friendly. Perfect English for us thick british. Exceptional service and the gentleman making the cocktails should have a pay rise. Top level drinks with a smile. The room was upgraded for us and I've stayed in smaller flats. Immaculatly clean and well designed. Free bike hire was very useful. Book this hotel!!! Great value and the staff made it for us. 5 stars.

Car parking was over the road when the parking directly outside was paid for. No big deal really. Its 2km odd from the old town for sight seeing. A bit far to walk for some. Free bikes and good bus links help this but its not central old town. Its main road location was great for us as we hired a car. Zero road noise.

Our experience at this hotel was wonderful. The modern and stylish decor created a lovely atmosphere. The staff were incredibly kind and helpful throughout our stay, always ready to explain things or assist us. We were delighted with the unexpected upgrade to an apartment and the complimentary parking. Having the option to charge our car (even with a charge) was a real plus. The hotel is located a bit outside the city center (which is perfect for a nice evening walk) and it's very convenient to reach by car from the highway. We'll definitely come back if we have the chance and recommend it for a delightful stay.

I got the individual room in the underground and it was very good! furniture was well arranged ao the room didn't look small. shower and bed we're good too. I also loved the amenities (slippers, cotton swabs, moisturizer,...)! very nice touch. the common areas were also very pleasant.

breakfast was a bit expensive (18 euros). I wish they offered a pre-set option, so it could be cheaper then the "all inclusive" breakfast version. location was good if you have a flight to catch, but it was a bit far to walk to the center. other than this, everything was perfect!

Very very nice hotel, we were surprised, everything was good, smelling nice everywhere, the room was super cool with everything that you could possibly need, most importantly small things like slippers and body lotion was a good touch😁 the service nice, friendly, we also had dinner there in a restaurant it was very good. The decorations all over the place are just so good and unique. Recommend this place to everyone, thank you very much

The location is far away but it's not very complicated to reach, public transport served us very nicely!

I highly recommend this hotel based on my recent stay. The entire crew was professional and kind, especially the front desk staff Denis. His warm hospitality made every day feel bright and welcoming — he truly made every guest feel at home. The hotel environment was clean, stylish, and had a good vibe. It was surrounded by several large shopping malls, and the taxi from the airport cost only around €30. Honestly, I regretted not booking this hotel earlier!
