Our stay was great. the building is in a busy area, but the apartment is quite. the location is very central, its accessible by all public transportation in Athens; metro station at your doorstep, taxis are always available at the main street. you can pretty much walk to anywhere you want from the apartment.
The apartment was clean and comfortable, the host provided all the basics you'd possibly need for your stay. the kitchen was fully equipped for light cooking, even had an espresso machine, which is great for us, because we love our espressos in the morning.
Wi-Fi connection was good, and we didn't have any issues at all throughout our stay.
