My boyfriend loved this Airbnb so much. The bed was cozy and so was the apartment. The bathroom was huge and the hot water never ran out which is needed after a long day of wandering. The location was perfect and central to the main attractions with ruins scattered throughout. We were so close to all the monuments but didn't have to deal with all the tourist traffic and noise. I'd say no more than 15-20 minutes walking to the colosseum, many of the churches, Spanish Steps and Trevi Fountain. Many bus' are only a couple minutes away, so if you don't love to walk and get lost in the streets like we do, then this is great as well.
The host was also great at checking in on us and providing direction. We picked up the key from a restaurant around the corner from the home.
