This is the second time I have stayed with Barbara and Rino, and we had pleasant experiences both times! (See my previous review of this same location for further details.)
Barbara and Rino keep a very clean, safe, and welcoming apartment, in a great location. They were helpful before and during the stay and offered their services in numerous ways to make our stay as enjoyable as possible. I would definitely recommend their apartment to anyone looking to spend some time in Florence :)
