The place offers a cheap, but nice accomodation in Athens. It's perfect for a few days and it is well equipped. Communication with Mag was easy and he provided us with all details before our trip.
Just one thing you should note: When you walk to the city center (a 15-minute walk), you have to walk through a neighborhood which I would want to avoid at nighttime and if I was alone. We were two people and weren't out late at night, so that was okay for us.
