Alberto's place is in a wonderful location. Close to the Accademia Bridge and all the major sites. It was an easy walk to and from the train station. It is super quiet at night, yet close to a large plaza with plenty of restaurants and a supermarket.
The place was spotless, has well-stocked kitchen, comfy beds and A/C.
Mariana was very helpful and communicated promptly.
We would definitely stay here again when we return to Venice.
