The breakfast was good, though the variety was limited. Our room was clean with unique decor, but felt small for the price. Most disappointing was that none of the Hotels.com Gold benefits were recognized by the hotel during our stay. Gold members should keep that in mind.

Was very impressed with this hotel. Hotel was located in a safe area with loads of amenities on the door step. Room was spacious and very luxurious. Will definitely consider this hotel for our next trip to Athens.

Absolutely gorgeous hotel - the rooms, garden, breakfast room, garden, restaurant and bar! Beautiful details all over and I especially loved the bathroom. Amazing team who make you feel like home from the moment you walk in. I came on a work trip and chose the hotel based on proximity to the meeting location but would absolutely come back on holiday!
