Great space in San Marco which is in walking distance to shopping, restaurants etc. I was able to have a nice hot shower! Yay! Loved that. It was nice, clean and the croissants waiting for us the next morning were a nice touch. Yes it's on the 4th floor in a building with no elevator but it really isn't that bad of a hike. Just pack light or only take what you need for your nights in Venice.
I would def book here again. It was a positive experience.
