We agree with the very positive comments of other reviewers.
I don’t think others have pointed out that, although pretty central, the apartment is a stone’s throw from two small, frequent buses that traverse the city north and south of the river (C2 and C3 - from shaky memory). The 12/13 bus stops are less than five minutes away - the routes go around the central area including whisking you up to San Miniato. Both are a godsend in wet weather and old age.
A few doors to the east is a gem of a restaurant - check out the website and reviews of Senz’Altro.
