Morena was a wonderful host: she was there when we arrived, and had decorated the living room with a paper heart garland, as we had told her it was our wedding anniversary - a very nice touch, as was the bottle of Prosecco chilling in the fridge.
The pictures do not do the flat justice: it is spacious, quiet, clean, recently refurbished, and the small kitchen is well equipped. We found there was everything we needed to cook basic meals from scratch, though be aware there is no microwave (there is, however, a coffee machine... Morena got her priorities right :-) ! ) The bed is big and very comfortable. There was plenty of hot water when required.
The flat is at the top of three flights of stairs (travellers with heavy luggage, be warned). It is very central, about half way between Rialto bridge and the vaporetto terminal at Fondamente Nove. The nearest baker is about 30 meters in the same street as the flat. There is a good Coop supermarket on Strada Nova a few minutes' walk away, as well as a pharmacy and several other shops. The neighbourhood has a very homely vibe which we really liked.
Highly recommended.
