Ilias and his father were incredibly helpful - they were always easily contactable and had solutions to any issues we had. The flat itself is in a brilliant location (15 mins walk to the Acropolis with loads of restaurants and bars close by) and is spacious with a good kitchen. The beds were very comfortable - the only issue we had was related to the heat at night - one of my friends had trouble sleeping despite the ceiling fan and air cooler unit - but it was very hot (37 degrees during the day).
