Mario's place is an updated and spacious flat. I went with our family of 7 and had plenty of room for comfort. The flat was centrally located to the San Marco Plaza and many main shopping streets. During the day there was lots to do and many people around, but at night it was quiet in the flat. Only tip to provide is to bring or buy kitchen supplies such as spices and oils, etc. There are plenty of dishes, pans and such, but if you plan to cook you will need other essentials to do so. There are many restaurants in the area too! Working with Mario was a breeze, he had quick responses for my questions. I would recommend this place to others travelling to Venice!
