Serena is very warm and hospitable. She offered to pick me up from the airport for a very small fee, even though my flight was delayed into after 1am. She was gracious. The apartment is in a very safe area. It is 30 min walk from vatican city. about 20 min from central part of city. I had a little problem with navigation, only because two of the main metro stops were closed while I was there. Serena left very clear maps and directions. The shower was hot with great water pressure. She left a bottle of wine, which was very thoughtful. Everything you need is there. I had no problems walking late at night in the area. The area around her place is quiet.
