we stayed in a couple of Mario's places as we decided to stay one more night but the original one we booked was full. he let us check in early as we were swapping and communicated well. We had to collect the key away from the property but the directions were clear.
Both were lovely but this one was our favourite. It's got such cute details: it's spacious, and manages to be simple and have grandeur at the same time.
Really nice neighbourhood away from the touristy bits and calm as it's so near to the open water views toward mainland, yet although it feels quiet at the same time there's plenty of street activity to absorb at the same time and cafes /bars along cafe not far away. It felt a bit more "real world" than other areas of Venice - in a good way. It's pretty close to the train station and a boat stop. Mario communicated well over the app.
