The flat is in a great location, just by the river, and walkable in 10 mins to Trastevere and Parione, but without the crowds. It is in a quiet side street with no traffic, with a large comfortable bed. There is some minor noise from other flats but nothing unusual for city living. It is well heated and the bathroom is modern with a good shower.
We had a couple of small issues over the course of the week, but they were quickly resolved as Francesca is a very responsive and helpful host. She also kindly gave us a late check out which helped a lot.
Local places we enjoyed: the Orange cafe for breakfast; Trattoria da Paulo and Verso Sera for food; Vinaietto wine bar.
My only complaint would be the shortage of a personal touch / essentials on arrival. We got there on New Year's Day, most shops were closed, but there was no bottled water in the flat, and only a very minimal amount of coffee, tea; a few sachets of oil and salt. Otherwise it is a great spot in a fantastic city
