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!

A lovely hotel in the suburbs, out of the busy centre of Athens. Rooms have lovely decor, very clean and comfy large beds. Surrounding location is nice. About a 10/15 Minute walk to the Metro station, then you can be in the centre in about half an hour. Staff are lovely. Currently a refurb going on to build the swimming pool, but we were only here for one night so that didn’t bother us. Bet it will be lovely once finished! We’d definitely stay again.

A Memorable Stay at The Twenty One Hotel, Athens

had an amazing stay at The Twenty One Hotel in Athens! From the moment I arrived, the hotel impressed me with its inviting atmosphere and exceptional service. The highlight of my experience was the receptionist, Dione, whose professionalism, kindness, and warm hospitality truly stood out. She made the check-in process seamless and went above and beyond to ensure my comfort throughout my stay. The hotel itself is a gem—beautifully maintained with cozy, well-designed, and impeccably clean rooms. Every detail was thoughtfully considered to create a relaxing and welcoming environment. The Twenty Hotel is a perfect combination of comfort, quality, and outstanding hospitality. I highly recommend it to anyone visiting Athens and look forward to returning in the future!

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.
