We stayed here for a week, and we loved the apartment. It was very well located in the Acropolis area, next to Acropolis museum and metro station.
John was flexible with check in and check out time, everything was very smooth. He kindly provided us basic survival kit with nearest places in area (shop, bakery...)
We actually found the apartment to be even more spacious than what we thought. The kitchen has all apliences and was clean.
Parking is possible on the street. I highly recommend this place.
