I absolutely loved, loved, loved staying at Simonetta's. Her apartment is in the absolute best location - right in Trastevere, so close to the river and in walking distance to plenty of sights.
The apartment is well-equipped with everything you could need. It also had a wonderful and spacious terrace, as well as a laundry annex. Everything was clean and organized and tastefully done.
Simonette herself is absolutely wonderful. She made check-in and out very simple, was always quick to respond and her energy as a whole was simply warm and welcoming. I would highly recommend staying here and I would love to do so myself (except it's always booked!)
