If you're looking for a modest and clean B&B in the centre of Florence, this is it.
It's 500 metres from the Porta San Frediano, busses 6 and 13 stop right outside the door and you're within walking distance of the historical centre (but also far away from the noise and the tourists).
On the Borgo San Frediano there are numerous Trattorias where you can have lunch (best one is Trattoria Sabatino, right next to the Porta San Frediano).
Breakfast is not served in the hotel but at the bakery next door. You get coupons for every day of your stay and can have a small breakfast there.
The downside is that the "free wi-fi" only works in the common kitchen on the first floor, so it really should not be advertised as a plus.More
