Phaidon's place was in a great location--central Athens within easy walking distance to pretty much anything you'd want to see, yet didn't feel super touristy. The subway is also nearby, which was convenient. He left excellent recommendations; some of our best meals were places he'd suggested. The amenities in the apartment were nice, like a washer (incl. detergent) and a fan. The flat is up one staircase and there's only a tiny elevator; not an issue for us, but could be if you have accessibility issues. The only downside was the air conditioner didn't really work, and it got really warm in the apartment, especially the first night. After that, we opened all the windows and bedroom doors and it was better, but it would be really uncomfortable if it had been any warmer.
