The location is ideal - minutes from the taxi boat dock and right beside San Marco, the most famous tourist spot in Venice. Plenty of places to eat nearby.
The flat was clean and can fit a family of 4 - one of the rooms is very small and the other bed aside from the master is a sofa bed but it had an extra mattress and was comfortable. The AC in the Master was great and the shower worked well. It was nice to have a washing machine and everything dried easily overnight. We didn't really use the kitchen but it was nice to have a fridge.
The apartment is on the 3rd floor accessible by a tiny elevator and although there isn't a view (no water or square view) the location is what sells it. Definately a positive experience!
