An excellent experience ! Location is perfect, you have everything near by, All the hotel’s facilities are very well designed and practical. The rooms are elegant and the bed is very comfortable. The climate control is very efficient. Exceptional breakfast is served in the restaurant area, which was brilliantly transformed into my “office” area during the day and later on to the best dinning experience I had in town. The hotel’s restaurant is a must !! The private parking on site is definitely very handy!!! I will be returning very shortly! and I would definitely recommend it for your stay and you dinning

Hotel is completely new. The decor of the rooms is spectacular. Staff were so helpful and made my stay so enjoyable. I was in Athens solo for IVF treatment and the staff were so thoughtful and I made me feel like a VIP :) Breakfast is in the twenty-one restaurant which is such a beautiful restaurant. The hotel is in the centre of kifisia with plenty of things to do. Overall I wouldn't hesitate to stay in this hotel again.

From the moment we arrived until the moment that we left, three days later, the staff were warm, friendly, helpful and knowledgeable. They had the level of professionalism that one finds in the international hotel groups but the warmth at The TwentyOne seemed more genuine, more personal. The hotel is located in a leafy suburb, which is ideal in the hot weather of summer. The decoration and furniture felt like home. The breakfast was out of this world, with homemade cakes and savouries. The staff were welcoming to my dog, who liked them in return. Phoebe is a great judge of character.

I cannot think of anything that could have made the stay better.

Really good location, walking distance to the shopping area of Kifissia and really close to all kinds of cafe bars, restaurants etc. The hotel has been recently renovated in a modern stylish theme that is very relaxing and welcoming. Extremely good housekeeping and the rooms are kept clean throughout the day. The staff were amazing, really professional and service minded, made us feel very welcome throughout our stay. Breakfast is really good, and follows the general boutique theme of the hotel i.e not too wide a selection but with unique exclusive products that you wouln't normally find in other hotel breakfast buffets. Hotel restaurant and bar are top notch, highly recommeneded!

Imagine feeling like you’re in the countryside or forest but actually you’re in the heart of kifissia. It’s tucked away but in a fantastic location. Close to the metro, gorgeous scenery. Near parks and shops and restaurants. The staff were SO helpful. I had been emailing with them to book a bunch of taxis before the trip because we were in Greece for a wedding which was happening outside of Athens, and they were so quick to respond and helpful to book all the taxis. They also helped my older parents navigate the metro system which I know can’t have been easy ! The hotel was clean and so new, carpets felt like clouds. So many amenities in the room too. I can’t wait to come back once the pool is done.

Nothing !

The hotel Twentyone was truly an amazing stay and will be a very well remembered visit. The location is exceptional and parking was provided with ease. For such a newly opened hotel, they really did get everything right. The professional and friendly service, from cleanliness to room service to even a remarkable meal in their very stylish restaurant also on site. Having a member of staff available at all times when needed was very helpful. The room was beautifully decorated along with all up to date shower features well worth every penny. We will definitely be returning here. A very easy 5 star status! We wish you well in your new hotel. Thank you!

Loved everything about the property: the interior design is beautiful, the room was spotless clean with everything you needed, the staff was very nice and accommodating, the breakfast was excellent. The location is in a very nice area of Athens, far from the center but accessible with uber or bus.

There’s a few restaurants nearby that had quite loud music and noise until 12-01 AM. While this isn’t the fault of the hotel itself, it made for a less pleasant stay because we couldn’t fall asleep until very late. Closing the windows didn’t entirely help. The parking spots are limited (I think just 3 or 4), so we had to park on the street nearby on a free spot. The streets are very narrow and we found our car with the side mirror broken the morning we left. Again, not the fault of the hotel, just mentioning in case anyone else is traveling here by car to know what to expect.

General considerations: The Hotel is brand new and the location (Kifissia) is amazing for shopping and the restaurants nearby. During the Christmas holidays, the atmosphere is even more charming; the streets are full of people and life. The hotel has only 3 parking spots, so you need to book it in advance otherwise you run the risk not to be able to park your car. Accueil: The guests are welcomed in a cozy area. There is no reception desk but the staff welcome their guests sitting at a round table which gives a customized touch to the procedure. The lobby is clean and a delicate perfume spreads through the entire room. The room: We were accommodated in room number fifteen. The room was very clean and well decorated. Everything was new, the mattress, the linen, the bathroom towels, the furniture, everything. The only flaw was the wardrobe dimension. If you plan to stay more than 2 nights, it might become a problem. The Breakfast: The breakfast is served in the main restaurant on a buffet. Considering the low occupancy of the hotel (I haven’t seen any other guest during our stay) I would suggest to set an “a la carte” breakfast, for two reasons: 1 – you can give your guest a service they will not often have 2 – you save money and avoid to set up a buffet for two guests only. Usually the buffet works with a minimum of 15 guests. The Price: The room rate was a bit high. Yes, it was Christmas and the location is quite expensive itself but for a brand new hotel, which has to break the market, I think that a bit of discount could give a plus on booking.com. It goes without saying that the quality of this hotel is a bit higher than its competitors.

America Express in not accepted. This is something that has to be corrected because you cannot leave Amex customers behind.

Great Location 3 minutes to the shops and cafes,Very clean and very friendly staff!!!I will be back again!!!

The buffet had all I need for my Breakfast in the morning Just a small tip for the hotel about breakfast,would be nice to have assorted jam,honey,praline and butter,so would be easier for the client to be served and different kind of cake (5 days carrot cake)…not something special but different…all the rest were great !!!!

Good breakfast, great location, kind helpful service.

The rooms were good but a bit small. We were à group of 2 friends and despite the 2 beds which were grouped together, it felt like we were sharing a bed. A room with twin beds should be placed separate. Also the sommelier at the restaurant was knowledgable but was quite pushy recommending very expensive wine. The food was wonderful but the expensive wine didn’t live up the the expectation.
