Excelent place, very clean apartment with everything that is needed. The apartment is located 10-15 minutes to the metro and about the same from the entrance to the Acropolis. The parking spot was great, but a bit of a squeeze if you have a larger family car (especially if a neighbor parks in front of the parking spot). Demos is usually responsive, but sometimes a bit hard to catch.
The apartment is a bit noisy at night, even if double windows are in place for better soundproofing, due to it being close to the highway - but we were expecting that when we booked and it didn't bother us at all.
