I had an amazing stay at Matteo's place in the Monti district! The location is a 5 minute walk to the Colosseum, but just far off the path where there aren't too many tourists or isn't too noisy. It is a quaint location and the space itself was nice, but a bit cramped. Wifi worked very well and the beds were extremely comfortable. The bathroom was also very new and clean, and the shower had doors (whereas some Italian Airbnb's don't even have a curtain to prevent water from splashing out), so that was nice.
Communication with Matteo was wonderful, and we didn't experience any problems. I would highly recommend this place if you are looking for something that is just outside the main touristy area but is still close to the city center / things to do. Thanks for an amazing trip in Rome!
