Francesca's place is pretty great. The locations is very close to the S.M.N train station as well as extremely walkable to the rest of Florence. Francesca was great with communication, as well as sharing some tips for the area. Only downside we found was the street noise at night. Between the night life, street cleaning, and garbage collection, it became pretty noisy. However I found this problem in a few other places in Rome as well. I suggest you stay here but also bring some ear plugs.
