We had a wonderful pre-Christmas stay in Yannis and Helene's lovely apartment. Everything went smoothly with check-in and check-out, and Yannis and Helene are very kind and attentive hosts who responded to any questions very quickly and also provided us with very good and comprehensive advice on practicalities and what to see and where to eat while in Athens :-) Oh, and the view of the Acropolis from the apartment is precisely as amazing as you might expect from the pictures! I highly recommend staying in this apartment.
