Really great place to stay! its a little bit outside of the old town but in a nice quiet and calm area and since the metro is near, its no problem at all. I didnt meet serena, but her son was really nice and showed me everything and I was in contact with serena via mail! the appartement was very clean and really nice, it has everything you need for a short trip and i would reccomend it! (the bed was really hard so if you got back problems or dont like hard beds, that might be a problem)
