This is the perfect place to stay in Athens. It is directly in the city center, literally upstairs from a ton of bars and cafes. The furniture and decor is curated but comfortable, there are two balconies for maximum sunshine, and the kitchen is well stocked if you want to cook. Not to mention, the view of the Acropolis is quite breathtaking.
I've stayed in a lot of AirBnb's in the past and this apartment might be the best one in terms of quality, comfort, and value. Could not recommend more!
