We had a great experience here. The location is perfect—a couple blocks from the Acropolis Museum and the pedestrian walkway, easy access to the metro. We used it only once, and we were able to walk everywhere else (Syntagma Square, Monastiraki market, Ancient Agora, even Mt. Lycabettus). The extra half-bath is handy for a larger group. George met us at the apartment to show us around and also organized a ride to and from the airport for us.
It’s a bit loud, but you’re in a city, so that’s to be expected. It’s probably quieter than other areas (Plaka, Monastiraki).
