The apartment is small but very functional for two travelers, and has a lovely patio. It's in a very quiet location (up some stairs). The apartment is close to the Roma S Pietro station, but is about a 40-55 minute from central Rome and a 20 minute walk to St Peter's basilica (30m to the Vatican museum). The neighborhood doesn't have much nightlife, which is great if you like the quiet at night.
Lorenzo is a wonderful and accommodating host - he went above and beyond to make our stay comfortable and convenient.
