This was my fourth trip to Venice and this was by far the best hotel i stayed at.
Everything was perfect. The breakfast is very good, and the afternoon drinks and snacks welcomed after a long day of exploring. Very quiet location close to the Rialto. They even supply umbrellas.
The staff even surprised us with a personal note and a tray of cookies in our room for my wife's birthday. I hadn't told them anything about it: they noticed the birthday cards she had opened for the occasion.
Note: at high tide during the aqua alta season, you'll need boots to cross a shallow low point to reach the hotel.
