This review is a two parter. First, the good: Silvio was an excellent host. He scheduled everything for our arrival, including a driver and someone to meet us at the flat to walk us through and make sure everything was good. He was quick to respond to any inquiries and very helpful. The actual place is two apartments that are joined by a hallway. for a group of 7 adults, this worked perfectly. The building is old, unique. and secure. The location, unmatched.
Second, the bad: I slept in the left side apartments back room, the bed was comfortable and the room spacious, however, there was no AC. Rome in September is HOT. I kept the windows open but there is trash service and street cleaning EVERYNIGHT. I didn't sleep a wink for the entire 4 night stay. Too hot with the windows closed, too loud with them open. The last thing I'd like to mention is the wifi connection was extremely slow, boarding on nonexistant at times. For me this was no issue because I had a data plan, but for half the group, and most Americans traveling abroad, wifi is crucial.
All in all, the place was centrally located, large, and the host was great, just visit in the winter!
