We had a lovely 3 week stay in Sofia's apartment. The location was perfect for enjoying an authentic urban experience: A short walk from the center, easy access to public transit, many shops and dining options, and a lively area for an evening passeggiata amidst a younger crowd. And yet amazingly quiet. Other than the occasional soft jazz note, we hardly heard a sound. The apartment is well equipped for a family, with 2 full bedrooms (only one bedroom has a/c however), a large full bath and a half bath upstairs reachable by circular stairs.
Regret we did not get to meet Sofia, but she was very helpful and responsive to our questions.
