It was great! Iit was the best choice for Athens, no doubt. The apartment is really close to Acropolis in between two metro stations with plenty of tavernas around. The apartment was clean, and really cozy. On top of that they left water in the fridge and coffee.
I must admit that I was a bit concern because Tom is new in Airbnb and he doesn't have many comments. Additionally, we had to get the keys from a box and not face to face.
However, everything went well and during the time there the electricity stop working and we contact Tom (Spiros). They replied inmidiately and light was back in few minutes, it was actually the whole building. I would say that I felt that they took care of us better than other hosts even if we never met in person.
In summary: Great location, excellent apartment and responsible host. Definitelly recommendable!
