This is a super Athens Airbnb, both for the property itself as well as for Lynn, the owner. Lynn is absolutely wonderful. While in Athens, my wallet was stolen, and Lynn spent a couple of hours helping us recover from that, including helping us figure out what to do to replace my passport. She was patient and comforting during the entire time. And her perfect English made things much easier.
As for the apartment itself, I can't imagine a better location for a tourist. You can walk to the acropolis and agora in just a few minutes, or take the metro just one exit. The metro station is only a 5 to 10-minute walk from the apartment. There are lots of restaurants, a couple of nice grocery stores, and a great bakery just an easy walk away (roughly 5 minutes or less).
The apartment is small, but Lynn has used the space very efficiently. We were two people, and were comfortable for a 5-night stay. The wifi is good, and the bed is comfortable. It's an active neighborhood with road noise, so bring ear plugs for the best sleeping at night. She has a really nice microwave/convection oven in the kitchen.
It's a great combination for an Athens visitor - a very convenient apartment and a saintly owner.
