The house is in a great position, close to the city center of Fira (5 minutes walking) and with a free parking nearby. The apartment itself is in a beautiful and calm courtyard, with a table and some chairs outside for relaxing. Inside, rooms and bathroom are indeed small, but big enough for 3-4 people. Katerina is a great host, communicative and friendly, who really cares about making guests comfortable. We only had a problem with the bathroom, water wasn't dropping fast enough through the sink drain and since the shower isn't separated from the rest of the bathroom, we had a few uncomfortable moments!
Apart from that, the house is great and I would definitely advice it
