Nansy was just great. The communication was so easy - she answered quickly to all of our questions we had before arriving and during our stay. The building has a perfect location - close to a metro station (Kerameikos - 3 minutes) and a supermarket and it's within 15-20 mins walking distance from some of the must-see places of the city - the historic centre (Acropolis, Ancient Agora, Plaka district), Monastiraki square (where all the cool restaurants are), Syntagma square (25 mins) etc. The flat was well equipped, warm, with comfy beds and everything you need. I highly recommend it!
