The apartment is spectacular. Its huge, super clean and is done up very tastefully. There is a grocery store and 2 great restaurants just a few steps away. The Rialto bridge ( this is a center point) is 10 minute walk and the St. Marks square is a 25 minute walk. It's a quiet and very pretty area.
Linda is very friendly and cooperative and responds very fast on whatsapp. she also gave us some great recommendations on restaurants and sightseeing. All other amenities like Wifi, washing machine, kitchen, iron were perfect.
small cons - The dishwasher and the AC in one room were not working on the days that we were there. The AC in the living room was fine - so one of my kids slept there.
Barring that - it was almost a perfect stay - We would recommend the place to anyone who visits Venice.
Small tip - If you don't have too much luggage - walk to the apartment from the Santa Lucia station(15 mins). If you have luggage, take a porter. This is faster and cheaper than the water taxi.
