Very comfortable and cozy B&B run by a family, who were extremely helpful and knowledgeable about everything in Florence. They knew every restaurant by name including where they are and when they open. They also made reservations, which was an immense help.
The hotel has a happy hour every evening for the guests, which includes free drinks and snacks. This was a great event for me, since I traveled alone, and met a fantastic eating buddy there who was also traveling alone.
The room was small, but comfortable and clean. The hotel made strange noises at night though, which bothered me until I popped in earplugs. I'm a light sleeper though, so this might not be a problem for most.
It's around the corner from the market, and five minutes or less from Duomo and Uffizi/Ponte Vecchio by walking, so it's a great location. The real advantage here though is the fact that the family who runs it is so friendly, helpful and obviously masters of everything Florence. It's clear they've been doing this a long time, and take pride in their service. I would definitely consider this hotel again if I come back to Florence.
