We had a great time in Marco's appartement. Marco is very easy to communicate with and VERY helpful. His appartement is beautifully renovated, very spacious, and the location is perfect when you want to be a bit further away from the most crowded places in Venice.
The only minor detail that was a bit annoying is the noise of the shoes of the lady in the appartement above. But this comes with the older buildings I guess.
Highly recommended!
