The apartment is beautiful, completely customized by Domenico himself so that you get optimal use and comfort out of a small space. The wooden floors and ceiling beams are a gorgeous contrast to the modern stained-glass mosaic lighting fixtures. The bed is large and super comfortable, and the bathroom even has a switch that turns on jazz music while you shower!
You also can't beat the location--it's just a few minutes to all of the main tourist attractions (Colosseo, Pantheon), right next to the river (gorgeous views at night) and right at the top of one of the best bar and restaurant scenes in Rome. I had a bike so I could explore the city at will, but I rarely found the need to leave this area for nightlife.
Domenico is also a great host. He comes and cleans regularly, and if there's anything you need at all he's only a text away. I was expecting a delivery of something that didn't come on time, and he went so far as to call the company for me to track it and then arranged for a friend to be in the building in case it came and I wasn't around--waaay above and beyond the usual level of service! He also gave me great tips for the area, and volunteered to make calls in Italian for me (for reservations, etc) if I ever needed it.
Great experience, would definitely come back over and over again!
