I had a lovely stay at Charlotte's place. The room is basic, but the location is fantastic and Charlotte herself is wonderful and helpful, with all kinds of good advice. There is also second room that is rented out to a solo traveller, so with a little luck you'll have a buddy to explore Rome with. The internet is fast enough for Netflix which was a nice way to settle down after a day of walking. The one downside for me was the smell of cigarette smoke in the house, and after a few days also in all your clothes. But that may just be part of the Italian experience...
