Luca is a wonderful host. He kindly met us by our water bus stop. (This is ideal as Venice is notoriously difficult to navigate).
The apartment is to a very high specification and clean. The sofa bed is nothing to worry about, comfortable though out our stay.
The location is ideal, it is 5 mins from a main square, but far enough away from the hustle and bustle. Once you get your bearings, it is easy to navigate back to the apartment.
The bars and restaurants Luca advises are spot on.
Can not recommend enough.
