Elettra and her husband are fantastic (even though I didn't actually get to meet her). Her husband helped us to the apartment, bringing boots and meeting us at the vaporetto station when there was 135cm of flooding in the city. I can just thank them for all the help.
The apartment is absolutely fantastic, it's cute (my girlfriend and mother fell in love with it) and it had a nicely equipped kitchen, comfortable bedrooms, and nice heating. It was so nice it made me not want to leave. It's the best place I've stayed so far.
The location is superb, real close to the St. Marcus square, and there is a market in a street just at the corner, as well as pharmacies, bakeries, and restaurants. It was so great to be inside Venice and not have to catch a bus from Mestre (as I did last september).
Don't think twice, you'll get a lot more than you've paid for. These are amazing people hosting an amazing place.
