Demetris's place is in a really fun location (Gazi) that's an easy 30-minute walk (or an easy subway ride) to the Acropolis. The apartment was a great value (we paid about USD$52/night) and having a free washer and dryer downstairs was quite helpful. The Wi-Fi worked well, and Demetris was very responsive to messages. He also arranged for a pickup from the airport (for 40 euros, the same or cheaper than a taxi) which was extremely helpful since we landed at 2am. A couple of light bulbs weren't working, which made the apartment a little dark but I'm sure Demetris will replace them. In short, we had a great stay and I'd definitely stay in the apartment again.
