I stayed at a handful of BnBs on my journey through Europe. While all of my stays were pleasant, Tina's place stood out on top. Her and Diego were very warm and welcoming. They take great care as hosts, not limited to keeping the space clean, offering a wealth of suggestions on how to make the most of your trip, and having great amenities.
If I'm ever staying in Florence again, I would seek out this room before anything else.
