Michele was the perfect host. A few days after I got there, the TV wasn't working properly. I called him and the next day he arrived with a new cable box that he installed immediately.
The flat itself was nearly perfect: on the ground floor, fully equipped in every way; the bathroom was a bit small but there was hot water and plenty of it. Located in Trastevere, there must be 30 interesting restaurants within half a kilometer in any direction.
The only problem for a partially handicapped person like myself is that Trastevere has streets of cobblestones which are both uneven and slippery; I had a hard time negotiating the streets. If you are an average person, though, this will not be the slightest problem.
