Fantastic location, very close to St. Mark's Square, the Basilica, and Rialto Bridge. The apartment overlooks a canal which makes you feel like you're in the heart of Venice. I went with my daughter who slept on the sofa bed, so we each had separate bedrooms.
The only negative with the apartment was the shower. It was quite small, had very little water pressure, and the drain didn't drain very well. I often had to turn off the water mid shower to let the drain catch up.
Other than that, everything was amazing!
