Perfect apartment, beautifully furnished and decorated. Rosa is a lovely host, very welcoming and available.
The place is very well equipped (kitchen +bathroom), comfortable beds (much appreciated after a walking day in Roma). Trastevere is a great area, where you can find many good restaurants + nice breakfasts just at the corner. (we loved going to Gisela's)
Markets are at the corner too. There is also a company offering locker services for your luggage a few minutes away, very handy too.
