The appartment is located in an older building (without elevator for people that have some mobility restrictions) but it is fully renovated and super clean! Small but enough for the two of us and it has everything we needed. Location is perfect for us and we truly enjoyed our stay. Dimitris is very friendly and super responsive host, he was always willing to provide more than requested info to help us have a great time, he also offered to move our lugguge up and down the stairs and he is very polite! We had the chance to meet his mum too and she is very sweet and she had offered us some Greek traditional Christmas sweets that she prepared.
Next time in Athens of course we will go back :)
