Great location, and very light and large apartment. Also, all amenities you would expect in an AirBnB apartment were present.
However, the big issue was the uncleanliness of the place. The bathroom, incl. the toilet seat were full of (pubic) hairs of the previous guests. The sleeping room features a wall with black mould, which can develop easily in Venice, but should be taken care off quickly. No excuses.
Bottom-line: if they get the cleanliness under control, this will again be a highly recommendable place
