The cozy flat in Trastevere was wonderful. It was clean, comfortable, bright and in an excellent location. Daniele's lovely mother met us and welcomed us to the apartment, communication was consistent and easy. The flat was well appointed and we were left with coffee and a few basics to make us feel welcome as well as some excellent restaurant recommendations. I would definitely recommend this place and hope to return again when we are in Roma.
There are quite a few stairs, which may not be for everyone. While we loved being in the center of Trastevere, I can see how this location might be loud in the summer months. However, it was easy to get to, and easy to explore Rome from this location, many restaurants and cafes within a stone's throw.
