Laura and her apartment are both lovely.
Her apartment is perfectly located, close to Ponte Sisto in Trastevere. The street is close to shops and restaurants. It is a little loud, due to the restaurants and bars nearby, but still easy to sleep. Laura has anticipated your needs and has wifi, a washer, hair dryer, adapters, etc.
Laura herself was so charming and hospitable. She helped coordinate airport transportation and made recommendations with restaurants and activities.
I would be happy to stay at Laura's Le Casette du Trastevere again.
