Traveller reviews
Eva “I had a very good stay at K29!”
07 May 2026
I was most impressed by the amazing hotel staff. When I mentioned that my neighbours were very noisy they did everything they could to make me more comfortable. After the neighbours checked out they made sure that for the last two nights I wouldn’t have any neighbours. My room was very pleasant and clean, and for me it was on walking distance from everything I wanted to visit. Breakfast was good!

Thanks for our stay! The staff were exceptional - polite, open and ready to help. All our extra queries were addressed promptly: when we asked for wine glasses or to keep our luggage after check out or to help to charge our phones before heading to the airport. Location is good too - everything is within walking distance. And finally the hotel promoted our standard room to a double at no extra charge. Well done and thanks!

The Athenaeum K29 is located slightly outside of the touristic center. The main street towards the centre is pretty lively and about a 15min walk. Theres a metro station close by too. But the side streets seemed sketchy as. So we rather avoided them because it felt rather uncomfortable to walk them. But thats the only downside, if you can even call that a downside since its pretty common sense where you should and shouldn’t walk. The hotel itself is clean, has helpful staff and really good breakfast with a midsized selection, but it tasted fresh and delicious. The Gym on the roof top not only offers a great view, but also has enough equipment to get a good travel session in. Pro tip workout at Sunrise or Sunset. Ask the staff, you wont find it otherwise. The room was big and had a comfortable bed. Traffic wasnt too bad at night and the sounds were not too loud for a 5 Million people city.
Odette Sarah “If we ever visit Athens again, we would use the same hotel as we are satisifed with our stay.”

They have many options at breakfast. It is a good buffet breakfast. Although it is exactly the same everyday, there is enough variety for you to not get bored. The staff at this place are absolutely wonderful and helpful people. Their warm and friendly hospitality made our stay a very pleasant one. Thank you dear staff for being positively unforgettable.
