We had a nice time in Athens ! Nasos place is very well located. I do recommand to stay in Plaka during your stay in Athens. The flat is lovely and comfy. It is small but tidy and well organized with all necessary equipment. Nasos is really considerate and welcoming. He gave us lots of informations for check in and the flat was easy to find. He also sent us some nice tips and nice adresses for our stay in Athens !! I do recommand this accomodation !
