Konstantinos's place is simple/minimalist but clean and comfortable. The location is excellent. You are basically in Plaka/Monastiraki and can very easily walk to restaurants, cafes and shops. There is even a little view of the Parthenon in the distance. It was also extremely easy to get to the airport shuttle and metro system (4 minute walk). It is important to take into consideration that since you are right downtown, it is a bit noisy and bright at night, but that is to be expected. Ear plugs and a face mask can help a lot for the light sleepers like me. Konstantinos was courteous and friendly. His building/the hallways are in a transitional/renovating stage so there are materials around but inside the room you would never know. All in all, a comfortable and convenient experience in a location that can't be beat.
