We stayed 4 weeks in Steve's apartment and had a great time. The flat is located just off Exarchia square (the area is heavily tagged but we felt completely safe, do your research about the neighbourhood) with restaurants and supermarkets in walking distance. It's about 30 min to any of the main neighbourhoods of Athens and tourist attractions, part of the way is pedestrian. There is a wonderful AC in the living room, which connects to a bedroom so that both rooms stay fresh. The second room has fans and is more quiet as it gives on the courtyard. The kitchen is big but could be better equipped. Steve and his mother have been wonderful hosts with plenty of great advice on the city. They even provided us with an extra desk so that both of us could have a dedicated workspace.
