Although we had seen the pics on Airbnb, we felt a little weary when standing in front of the address: no front door, only an iron shutter gate with graffiti in between buildings that clearly had seen better times. The apartment however proved to be as great as the pictures suggest: modern and spacious with a nice balcony with an Acropolis view. The host Alexandros was moreover great to communicate with via Viber. He also provided an online guide with more info on the apartment and with some suggestions of nice places for eating or having a drink.
The location of the apartment is also great to discover all the Athens highlights and easy to reach by metro. Close enough to the busy Psyrri bars but far enough too in order not to bothered by the noise.
Great place to stay, would certainly go back !
