Luis was a very kindly host, he was very flexible with our check in and check out, and gave us a lot of tips and directions of Rome. His apartment is very well located, especially because of restaurants around Trastevere neighborhood. We've gone to everywhere walking: it's 25 minutes walking from San Peter basilica, 20 min from Coliseum. It was very clean, but it had a little mold on the walls near the bed, this may not be a problem if you are medium allergic and will just stay there for a 5 days. It doesn't have a washing machine at the apartment, if you need it you have to go to a laundry. Besides those things I would recommend Louis's apartment due to location, cleanliness, and his attention.
