Alessandro was a great host, possibly the best I've had. When we met he gave me a mini tour of the area and told me where I could find things. He was usually very good with responses and gave great recommendations.
As others have said, the apartment was a little small but worked just fine for 3 persons for a weekend. The location is great, especially if you plan to go to the Vatican but it's also easy to get to other places via bus or even if you are up for walking.
