This was a great airbnb experience and I would definitely recommend it when visiting Venice.
A lot of hotels and airbnb's in Venice seemed overpriced and unkempt, so I was really happy to find this place, which was charming and updated, big, clean, affordable, and in a really great location -- 15 minute walk to the center of Venice's tourist attractions but near a very charming Piazza (S. Margherita) that was full of restaurants, cafes, and local university students. This was my favorite part of the city and the apartment was a very comfortable place to come back to.
We were a little worried when the host first led us into the building since almost every other floor appears to be under construction -- we didn't hear any noise whatsoever but the building's entry staircase feels like walking through a sort of dimly lit unfinished attic/basement. However, when you get to your unit near the top, it's bright, airy, modern, and renovated, so I wouldn't let the building/ entry scare you off.
Piece of advice for people visiting from US: have the host explain the thermostat to you at check-in. We're pretty handy but just couldn't figure out how to use it and had one cold night before she came by to set the heat on.
Otherwise, my only real complaint is that they don't provide any shower soap or shampoo. It wasn't a big deal to go out and buy some but that would be a pretty cheap and easy way to make the stay more comfortable.
All in all, a great stay.
