We have stayed at Christos' apartment for a week during September. The apartment is large and well-furnished. There are all amenities that one could wish for (and some extra) -- including multiple coffee makers, great WiFi, excellent air conditioning and spacious bathroom.
The location of the apartment is very good -- it is not quite in the center of Rhodes, but this is an advantage as the area is more quiet and you can taste more of the local flavor. There is a large supermarket a few steps from the door and lots of restaurants and cafes to eat in (they are cheaper in the area compared to Rhodes center as well). A bus stop with a direct connection to both the airport and city center is nearby.
Christos was a wonderful host who greeted us himself on arrival and provided clear instructions on travelling to and from the apartment. His mother even baked a cake and his father left us a jar of delicious peach jam! Christos also stocked the apartment with some food, which was much appreciated after a long time spent travelling.
We would recommend Christos' place to anyone who wants to have a very good and comfortable stay in Rhodes.
