The room is okay for a few days. The check-in was super easy an Mag sent me a very detailed description for the way to the apartment in advance. Unfortunately he did not answer when I asked him something during the trip. The bed is not the comfiest but the room has a smart TV. The location is nice, there's a bus stop right in front of the apartment and a nice restaurant/bar area in walking distance. Just the supermarkets are a bit further away. Slightly annoying was that the WiFi didn't work properly most of the times.
All in all the room is fine for a low budget trip to Athens, but don't expect too much modern comfort.
