I originally rented the room on the 4th floor. However, given a small mishap we were able to upgrade to the 5th floor apartment. I wasn't a big fan of the room on the fourth floor so I was thrilled when I saw the apartment on the 5th floor. If you have a chance to rent the 5th floor, do so! The location near the colosseum is super helpful. Stefano is also responsive and was flexible with the check in when our travel plans got delayed. The working elevator was also helpful.
