The flat is very well located and it has everything you need. It's located like 2 mins walking from the tube station and everything that you need to see and do in Athens as tourist is just around the corner.
Phaidon is an amazing host. He picked us up at the tube station and took is to the flat. He also offered himself as a guide and he recommended us many places to visit.
We would definitely come back to Phaidon's flat if visiting Athens again
