We stayed here for 10 days, and would always come here again. Maria was always incredibly quick to reply to our questions, and her brother George helped us a lot during our stay. It's a very well maintained apartment that lacked pretty much nothing. Location-wise it's not incredibly close to any metro station, but whether you need the blue line (Ambelokipi), the green line (Victoria) or the red line (Panepistimio), it's all within a walking distance of 20 minutes (plus, there's always the bus). I'm very grateful to Maria and George, and would recommend staying with them to anyone.
