Yiannis is quite possibly the most responsive host ever. I would receive responses within 15-20 minutes of them being sent! The flat is super comfortable and Yiannis was quick to rectify the brief issue we had with the wifi - quick enough that we didn't even notice it. :) It is in a very nice location, right by cafes and supermarkets and a very pleasant 20 minute walk to Plaka (the old town) through the botanical gardens. We thoroughly enjoyed our stay here.
