Bred is a great host and his place is amazing as it was built in the 14th century. The location is fantastic as all the tourist sites are within 15 min walking distance and is close to the central Firenze train station. The only thing you need to consider is whether you're a light sleeper. Due to the age of the building there's no sound insulation built in, so int he morning when the merchants lug their carts to the leather market (just outside the door) you can hear all the carts on the cobble stones. There's also another room in the apartment, and since there's no sound proofing you can hear other people laugh, snore, their TV etc. So if you don't mind noise and you sleep like the dead then it's the perfect place for you. Otherwise, maybe bring ear plugs.
