Mario is an excellent host! He met us at the Ospedale station and from there it was a quick walk to the apartment. He gave us a your along the way, pointing out the supermarket, the way to San Marco and other points of interest. He was very helpful and knowledgeable.
The apartment was perfect - right on the canal! We enjoyed sitting on the couch in the living room with the windows open, enjoying the sights and sounds of Venice. There tend to be Mosquitos so make sure you use the insect repellent plug in (bedroom) that Mario provides. We did not the first night and woke up with many bites. The second night we had none!
This location is perfect if you want to stay off the beaten path from the tourists. It's a walk to San Marco but we only went there once. We very much enjoyed the area surrounding the apartment. We stayed the first two nights of our honeymoon here, and will be back the last night to stay in Mario's other apartment!
