Me and my sister stayed at Fabrizio's place during the carnaval. His place is well located and very nice, away from the noise but very near to everything you wanna go. Fabrizio is a fantastic host, he gave us all informations we need and answered all our questions, we would love to come back in Venizia.
We even stayed one more night at the San Marco airport, all planes were cancelled because of the snow ! We won't forget our experience in Italia. :)
