Double thumbs up!
Roberto was very helpful and friendly. We were late for half an hour, and he waited for us at the Guglie water taxi port. Besides what is listed in the amenities, he also left a couple umbrellas and water boots in the apartment for us to use. Though we didn't need them at the time of our stay, you can tell how considerate Roberto is by leaving them for us.
The apartment is clean, in a very convenient location and at the 2nd floor of a historical building. There are restaurants and a market right downstairs. I felt like I was living as a local. Every time we saw tourists pulling their luggage and trying to squeeze themselves through the narrow allies, we appreciated how close we were to the water taxi port. The apartment is 2 mins walk to the Guglie water taxi port, 5 mins walk to the train station. And this water taxi port is one of the closest ports to the Venice airport. The farther eastward you stay on the island, the less convenient it is to get in and out of Venice.
We would love to come back and stay in the apartment again. :)
