We have spent 2 nights at Romano's place. Alex welcomed us and was absolutely great (gave us a lot of information and good tips about Athens)! The apartment is very well located. Other than that, the apartment is old, the bathroom and the facilities are very basic, no A/C in the living room (not easy in the hot Athenian summer) and we have had several shortcuts when turning on the A/C in the rooms.
As our stay in Athens was short it was not a big issue but we expected more what we've got.
