We spent three nights here and it was just what we needed for a family of six in Venice.
We are two adults and kids ages 14, 12, 10 & 7. Two of our kids slept on the sofa bed in the living room. The apartment itself is fine. Clean, functional. We used the roof terrace on the top of the building to eat a couple of times and this was really nice. (It is shared by the whole building we didn't see anyone else up there).
The location is good. Nice and quiet, but only about 15 minutes stroll to the main sights. And everything is so lovely in Venice. It's really nice to explore a little off the beaten track.
The Aircon was efficient really necessary in Venice in August.
Overall I was really happy with our stay here, no complaints.
