Pros-lots of space for the price. It’s also a fairly quiet residential/student neighborhood that’s a bit off the tourist track but still close to many sights, so that could be a plus depending on your needs.
Cons-it’s not ‘dirty’ but furnishings a bit worn and dishes a bit used/greasy. Depends on your standards for comfort. The internet is also painfully slow, took forever to load pages and frequently cut out.
Overall, it was a good base for a few magical days in Venice and it’s definitely good value. But depends on expectations.
