Such a lovely place, such a great host!
We stayed for about a week and had a great time. We are also AirBnB hosts and we learned a few things that we want to do for our guests!
First, the apartment is lovely - the art and decor make it clear that you are living with an artist who values the design of everything in her space. We were welcomed with great instructions. The guidebook provided was used many times, and the guest book had several great comments from previous guests on things to look for (and things to avoid!)
The location was great for exploring Athens - easy walks to the Acropolis, the Acropolis Museum, and the ancient Agora. Great restaurants close by as well. Other tourist locations were a short cab ride away - we used cabs for most of our trips, and also enjoyed renting a car for a trip to Delphi (highly recommended!) and to a local beach. We didn't use public transit, but there is a metro stop close by (3-4 minute walk).
We will definitely stay here again the next time we stay in Athens.
