This listing is in the middle of the Cannaregio district of Venice. It's a little quieter and less crowded than many of the other areas of town. Venice is easy to walk, so even though we were on the opposite side of town from San Marco, it's only a 20 min walk. We loved getting a little lost in the little alleyways where there were no people only to reemerge to see thousands.
The space looks like the pictures, but I will say that the ceilings are very low. I'm 6ft and had troubles fitting in the shower and getting to and from the bedroom. However, we'd stay here again because who goes to Venice and stays in the room all day? It's a great value.
