I had a great experience staying at Luis' apartment. The room is spacious and the queen bed is very comfortable. The location is perfect as it is right next to the trastevere restaurants, bars, and shops. It is also easy walking distance to the pantheon/campo del fiori area as well as the Vatican. My only complaint was the lack of hot water in the shower, but apparently that's a problem throughout rome. Luis is a very helpful and responsive host, and I would definitely recommend staying at his apartment.
