Great location to stay in. Walkable to all main attractions. Host is great, however we dealt with someone else the host had organised. We requested an extra guest and couch bed was available for extra $ which we appreciated. We also asked to leave our luggage in the apartment for longer than check out as we were doing the Vatican in the morning. This was much appreciated.
Note that you will be required to pay city tax. So make sure you are comfortable paying the about.
Thanks
