I stayed at Casa Cimabue three days. It's conveniently located two tram stops almost next to the Flaminio metro stop in front of Piazza del Populo. The apartment is in a 1930s building, in what I would consider a residential area. The room had been renovated and was very clean. There is a coffee machine (coffee, tea provided), refridgerator, and selection of pastries; in otherwords Italian version of breakfast. Area was quiet and host helpful in all regards. Note that when you take the #2 tram for first time, be aware it stops at a couple of major street intersections, initially making the "2 stops" a bit confusing. Otherwise transport was easy.
