We enjoyed our stay at the Prime Vatican Garden appartment in Rome. The appartment is large, well stocked, cool in the summer, and very central (under 10 minutes walk from Vatican City). It is unexpectedly quiet at night, so we slept very well. It is also expected to be quiet, as everywhere. Street parking is free at night and acceptable at day, you just have to hunt for a spot, but we always found one nearby with a bit of patience.
