The place is really walkable to all the main sights. For those who bothers walking too much the nearest metro station is about 10 minutes walk. There is also a pretty pizza bar right at the corner and a couple of supermarkets near it. The cleanliness of bathrooms depends on the people you live with, just fancy your chances.) To sum up the Patrizio’s place really worths its money, if u visiting Rome for a week or so.
PS: There is a little problem with hot water in the shower :)
