Franco is an excellent host. He helped us a lot with transportation, his driver is very kind and worth every penny. By arrival he provided a bottle of red wine and Nuttela and cheese for the kid, very thoughtful.
The flat is very well located ans spacious, in walking distance to most of Roms sights. It is loud because of teh traffic, sure, but with earplugs I did not heard it.
I totally recommend the flat and Franco!
