Nikos' apartment is located as centrally as it gets, only a couple of minutes to walk both to St. Mark's Square and to the landing docks of the boats to the airport. The place is remarkably clean and tidy, even though you can tell it is only let to tourists. Thus, expect a functional flat rather than a cozy nest.
Nikos is very professional: fast to respond, efficient, yet helpful and kind.
Together with our 15 year old daughter, we stayed at Nikos' for two nights in fall, and we would definitely come back.
