Great place to stay in Athens. We were a family of five and Panos was particularly helpful and made sure we had everything we needed. We had a breakfast ready when we arrived and he reserved for a taxi van to the airport, which were particularly appreciated.
The apartment is clean, spacious, with a great view. You can go to the main attractions with a 30 min walk and/or take the bus (5 min walk)/subway(15 min walk).
