If you are looking for something conveniently situated this is a great option. The hosts were responsive, helpful, and very pleasant. They also put together a really handy guide of their favorite food and drink places in Athens, which was a great way to get a local flavor of the place.
My husband and I stayed for just one night, so we were okay with the room not having an en-suite bathroom. We also had access to the entire place even though we had only booked the room. I would recommend staying with Lilly, Giannis and Mimi when in Athens.
