If you expect a hotel stay, maybe book a hotel. Francesco's flat was a genuine experience in the San Lorenzo neighbourhood- lots of nice cafes and nightlife to be discovered nearby. Would not recommend to super light sleepers- it's on the ground level and could be noisy, and the roof in the bathroom is a bit short- tall people beware! Although it's a bit far from the old centre, it's a reasonable walk to the colosseum and really quick to get to the central train station.
