Konstantinos, was very friendly! Even though I grow up in Athens, was a bit stressed as I had low battery and I was afraid that couldn't get in touch with the host. Konstantinos made things easier as his instructions was very good and he shorted a charger for me in the coffee place across the studio!
The studio was very clean and ideal for my stay in Athens as is located in the centre and is within 3 min walking distance from Plaka and all local bars and restaurants are very close!
I would recommend this place for visitors that want to explore the city centre of Athens and mix with locals!
