The only negative of our stay at Roberto's place was it wasn't longer. Since we had a cancelled flight we only got to stay a day and half.
Without a doubt the greatest appeal for Roberto's place is the Gondola's passing by the window all day long. Its an awesome experience you wont forget.
The loft is also very east to get to on the water shuttle from the airport if you take the orange line. Roberto helped me out with knowing how to navigate this. And easy to get to the train station on the ACTV water bus.
Also east to get around to all major sights. Would return.
