The location was absolutely perfect - you really are in the heart of Venice which is extremely convenient if you want to explore the area properly for a few days.
The main issue was that there wasn't a proper kitchen to make meals - we only had a fridge and a microwave. Also, to clean any dishes we had to use the bathroom.
Further, although the rooms were quite beautiful the sound proofing was quite bad, we could hear the rooms on either side of us very easily.
We would recommend this place for a shorter stay in Venice.
