Christos and Vivi are possibly the most deicated hosts I ever had on Airbnb. Our flight arrived at 2am and Christos came to pick us up at the airport (in a taxi he arranged) so he could give us tips on our trip on the way to the apt, amazing. They were extremely attentive and helpful.
The apartment is very spacious, perfectly clean and comfortable. It is at walking distance from the Acropolis and Plaka, on a street with no cars but very centric, which also means also that Friday and Saturday night can be a little noisy in the front bedroom.
The beds are very comfortable, AC works like a charm and the kitchen was also very practical.
The bathroom is maybe a little small for such a big apartment with a small shower, but spotless and functional. We didn't get to use the sauna but it is brand new and clean.
Would definitely recommend this place and come back on my next trip.
