If you are in Florence you should definately stay at Bred´s place. It was our first experience with AirBnB and it was just perfect.

Bred´s appartment is well located, very close to the main station and just one minute walk to the Duomo.
Bred is very nice, relaxed and it was fun hanging out with him and the Karaoke Machine ;-)
He also knows where to eat, where to order good pizza and the best Italian beer brands :)

We would definately stay there again!
