Horacio's apartment is spacious, with three bedrooms, we were able to sleep our large group of 10 very comfortably. The apartment was tidy, and the kitchen and bathroom very clean.
The apartment is well located, five minutes away from the San Stae water boat stop (with a boat to the airport), around the corner from the beautiful and highly recommended Ca' Pesaro art gallery, and ten minutes walk from the Rio Alto bridge. Living here for a few days gave a taste of what it must have felt like to be a local in Venice, as the apartment is right by a canal, amongst beautiful, small, winding streets.
Horacio was a fantastic host, who communicated promptly and in great detail before and during the trip. He was kind enough to pick us up from the water boat stop to take us to the apartment, and gave us recommendations for things to do locally. I fully recommend this apartment, especially if you are in a big group.
