We enjoyed staying in Monti's Chic Nest. Valerio owns the place but his parents manage it (and they live immediately next door so they're very easy to get hold of). The apartment was comfortable and was very centrally located, making it easy to walk to all of the sights. We had minor difficulties with the laundry but we were able to get help with it right away, which was nice. Additionally, the hosts were kind enough to hold our luggage after we checked out so that we could explore the city some more. There were some language barrier issues (we only speak English) but everything worked out in the end. We would definitely consider staying here the next time we're in Rome!
