Gianluca's place was great for us. The location is quiet and out of the hustle and bustle, but it still had lots of restaurants around, a 24-hour grocery store 2 blocks away, and was about 100 meters from the (very frequent) metro. It was also entirely quiet.
The bed was very comfortable, the bathroom was decently sized (especially for italy), and everything felt nice, clean, and in good repair. Also the room felt very private, with a lockable entrance immediately after the front door of the apartment. It was a very comfortable place to spend a few days.
Finally, Giancarlo was an incredibly nice and welcoming host. We were already arriving on the later side, and then our train was severely delayed, such that we arrived even later. But Giancarlo stayed up to wait for our arrival, and was super friendly when we finally got there. We couldn't have asked for a nicer host.
We highly recommend this airbnb if you are staying in Rome. It was perfect for us.
