We stayed at Fabia's place for 2 weeks, which happened to coincide with one of the highest 'acqua alta' events Venice has seen in many, many years. We can confirm that even though the apartment is on the ground floor, the acqua alta did not even reach the front door of the building, let alone the interior of the house. Hopefully this is some reassurance to prospective guests.
The house itself is very comfortable, and you can tell a lot of care was taken in the furniture and amenities. There is tons of good storage space for clothes, the bathroom is big (especially by Italian/European standards), and we found the bed quite comfortable, especially once we figured out how to use the air conditioner unit.
The weather was not great while we were there, so unfortunately we didn't get to use the patio much, but it was nice for the few times we were out there and is a good spot to dry clothes, assuming the weather cooperates.
The location is good for exploring Dorsoduro, or for hopping on a vaporetto and going elsewhere on the island or in the lagoon. The vaporetto stop is a 3 minute walk from the house, and the one bridge has a ramp built onto it so you don't even have to deal with any steps. (We had a LOT of luggage so this was helpful.) There are great restaurants in the immediate vicinity (Pane e Vino / Trattoria Anzolo Raffaele is excellent), and it's a very easy walk to more good restaurants near Campo San Barnaba and Campo Santa Margarita. Fabia provides several good recommendations as well.
Our only complaint about the house was that the wifi was not reliable at all. The internet connection is from a little hotspot device that depends on a good cellular signal. Since the house is on the ground floor and fairly surrounded by big buildings etc, service was spotty.
In all other ways, we had a great stay. Fabia was very responsive, before and during our visit. A friend helped with check in and check out, which were both very easy and smooth.
