We had a great stay with Lisa and Guido. They were great hosts and very helpful. The room was exactly as described and there was a great deal of privacy when you desired. They were also very helpful in making plans and just knowledge about Rome. Trastevere is a great neighborhood to be in this is a great place.
Make sure you go up and see the view from the roof during the day!! We did it at night and did not see it from the day and it was not as good.
