Thomas and Ksenia are outstanding hosts, with prompt replies, easy to organize with, great availability, amazing hospitality that includes useful local tips on what to see and where to eat that helps you find places that are both authentic and affordable, which is hard to do in a big tourist city like Athens. Their apartments are sparkling clean, with all amenities one could imagine and very stylishly decorated. It is the best airbnb place I've been staying at so far, and I've visited a dozen already.
