Gianluca's apartment was very special. We absolutely loved the design of the studio and the environment of its location. The studio is more specious than it seems on the pictures. We saw other reviews complaining about the noise from the bar downstairs but even though we stayed for the weekend the noise did not bother us at all. Back home we live in the city center and it was pretty much the same. We enjoyed walking around the neighborhood at nights lurking through the young hipster clubs and bars in the area.
3 things bothered us regarding the place - the wifi in the apartment was based on 3G infrastructure that wasn't strong, and most of the time it was very difficult using the Internet for basic things (tour planning, social networking, etc). I would recommend the host switching to static Internet infrastructure for wifi use.
Due to medium quality of the transportation in Rome, getting to and coming back from touristic areas took more than 30-40 minutes (apartment is located only 3km away).
There was no full body mirror in the studio which gave a little problem getting all chic like a true Italian :)
Other than that we were very pleased. If you are young, hip or a hipster - that's probably the perfect studio for you to stay in while in Rome.
