The apartment is beautiful and easily accommodated six of us. The neighborhood is quiet but close to many interesting parts of Rome. It was very easy to get around.
When we arrived the hot water wasn't working well and there was not enough wifi power for all of us to use it at the same time. I texted Nassir, who had greeted us when he arrived and both of these problems were quickly fixed.
Although we arranged this stay through Airbnb the apartment is managed by a management company called Rome Lofts, so you don't actually have contact with the owner. We were a little surprised to be asked to sign a rental contract through Rome Lofts when we arrived, but after reading the contract it didn't have any restrictions that were different from our Airbnb arrangement. We were also able to arrange a very reasonable car to the airport through Rome Lofts which was very convenient.
Just a warning, the apartment is on the 5th floor and although there is a lift, you still need to go down a short flight of stairs and then up a couple of stairs to get into the front door. The 2nd bedroom and bath are also up a steep flight of marble stairs, so this would not be a good choice for mobility impaired travelers or families with small children.
For us, it was great, we were even able to entertain some friends who were staying close by.
