I stayed in the flat for two weeks and all that time was just great. The flat is well equipped, you can find all necessary staff and even a first aid kid in the flat. The location is quite good, just few steps from the metro station, not far from the city centre, all main sights and shopping area. You can find supermarket and a lot of cafes/restaurants in the area. The area seemed safe to me. The communication went smoothly and effectively, everything was well organised. I can highly recommend this accomodation and would stay there again myself should I come to Athens again.
