We spent 3 nights at Kleo and George's apartment. George welcomed us in person and showed us the apartment. Everything is has described in the ad and the pictures. The flat is clean, the living is very sunny with a nice balcony. The bedroom was comfy but a little small.
We spent most of our time visiting Athens and we like to walk (we went to the Acropolis by foot, it takes 30-40min) so the location was fine for us, and if you don't like to walk, the metro station is not far. There are supermarkets, shops, bakeries and everything you need in the neighborhood.
