Florence is a very beautiful city and M&B is a perfect place to visit it. Close to the gare, not far from center and monuments.
The place itself is clean, tidy, convenient and very charming. I surely recommend it for who is looking for a guest house and I will surely go again if I have the opportunity to visit Florence again.
The tips are also very accurate, I strongly recommend these restaurants if you want to avoid bad food/tourists trap.
