The location is great, close to the Acropolis. The apartment is very clean and nicely decorated. Fani is very friendly, we didn't have any issue to find the apartment. We had to change at the last minute our booking from 3 nights to 1 night and she has been very understanding. It is perfect for a short stay in Athens !
The only remark is that the shower is not very convenient to use (no shower curtain). Also the apartment isn't well sound-isolated from the rest of the building, which makes it a bit noisy at night.
