Marco is an excellent host. When I arrived he showed me around the area in his car, and when my partner arrived in the evening he drove me to the airport to pick her up. He had lots of helpful tips about the area, about Rome in general, and about the public transportation system.
The studio, which Marco built himself, is beautiful. It's comfortable, cozy, and has a lovely view of the mountains. The neighborhood is quiet and there are great restaurants nearby. We had a great time in Rome thanks to Marco and his flat - highly recommend to other guests!
