Let me start by saying that I was looking for hotels around this campo (one of my favorites in Venice) and Mario's apartment (for three nights) was almost equal to one night at a hotel. Located centrally on a canal, the apartment has lots of space with two separate bathrooms and a cozy living room. All windows face the canal and have great views. As other reviewers said, yes: there is the trash boat in the mornings. It didn't bother us. And yes, there are mosquitoes, but you can bring repellent. But let me say there are mosquitoes everywhere in Venice including the hotels. Anyhow, I would stay at Mario's again, and Mario was great with communication: always ready to answer questions, and check in was super easy. It kind of felt like we lived like locals in Venice for those three days. It was that kind of place.
