This is the perfect place to stay in Athens. Panagiotis is a fantastic host and provided excellent communication throughout my time at his flat. The flat is clean, comfortable, and has a perfect view of the Acropolis. The location was also great for us. There was a subway station close by, but all the major sites are walkable (the Acropolis and Plaka were about 15 minutes by foot). There is also a police station and a small market right outside the apartment complex.
Thank you again Panagiotis!
