Ema and Stefano are really nice and friendly. I came to Venice on Halloween night, and Stefano picked us up at the Boat Station with some treats (Apple pie and pumpkin pie were good, thank you), then showed us how to get around and how to go to the house from the Boat Station; then showed us how to use everything in the house.
The house is a nice experience, it's totally wood and everything is pretty nice, I feel really eco-friendly here. This place is kind of big, you will have empty spaces to leave your stuffs around. The area is just 5' walk to the Boat Station, it takes around 15' - 20' to get into center but not that bad and great for experience.
I highly recommend to stay here when you stop by Venice.
