Everything was perfect with the aesthetics taking front seat. The ambience of the gardens, the service, the peace and quiet, the food and drinks, everything was absolutely amazing. The design of the room provides a sense of peace and easy luxury. The amenities were also top notch.

I dont have anything negative to comment on

The Twenty One is a lovely hotel in the center of Kifisia. The hotel's restaurant serves great food - and the venue is gorgeous with a huge outside patio area with natural shade from trees. Beautiful space with very relaxing vibes. The rooms aren't huge, but they are very well equipped and nicely designed. We especially enjoyed the boutiqueness of small hotel, paired with a lovely atmosphere and excellent food + there's pool :)

Our flight wasn't until the evening, and we checked out hours before departure. We got to keep our luggage at reception, but we weren't able to shower anywhere after checking out.

Spacious and well decorated room, really comfortable bed and a good amount of toiletries included. Staff was very kind, room service was quick and overall my stay was wonderful. Extra thumbs up for the little radio/speaker.

A hidden gem hidden among the trees of Kifissia. I had booked a simple room because I was traveling alone and I had a pleasant surprise of upgrading the room to a beautiful and romantic room.. I was ready to send a message to my wife to take the plane and come. We will definitely visit together next time. Now the most important thing you look at in a hotel is cleanliness and it was spotless. Perfectly functional and spacious with everything a traveler needs in his stay. Even though I only stayed 1 night .. that was great! Thank you!

I don't like to had be alone to this romantic place !!

We loved the pool, ambience, attention to detail, shower, restaurant, and trees. The staff were all very accommodating and made us feel welcome.

Everything…it’s simple and stylish.

I loved everything

This hotel is beautiful, modern, super clean and charming. I love the tiled pool and the breakfast buffet was top notch. The man who works in the restaurant is SO kind and goes above and beyond— he will remember your order :) always a nice feeling. The rooms were incredible. Super clean and everything was perfectly appointment. I felt this was a great rate for what you get! This is a suburb so expect it to be quiet and obviously away from the hustle!

Personally, I was surprised that for a boutique hotel that the front desk/check in staff was not very helpful or “warm” in personality. I needed help phoning a spa and the men seemed very confused and not helpful. This could be due to a language barrier, which I completely understand. The woman working in the evenings was helpful in assisting us in finding a tavern. We stayed at many hotels during our time in Greece and found the front desk people to be more friendly than this. The guy in the restaurant made up for it though :)

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.

Loved absolutely everything! This is THE hotel to be in Athens. Far from the crowds of the city centre, perfect if you plan to see Athens far from the toruistic areas. I travelled for work, so I was not looking for tourism, and this hotel has been by far the best I have been in the city.
