We stayed a Luigia's place on May.
The apartment is great. Living room & kitchen are well furnished.
Since most of the day we travelled we didn't spend much time in the apartment. There is a supermarket right next to the place.
Communication with Luigia was done in Italian for convince, ahe knows English, but written is better than spoken.
Luigia provide maps on how to get to the apartment, that take a bit time to understand and are very helpful if you take the Vaporetto to S. Zaccaria.
The kitchen was missing some essentials for cooking like oil (but had enough pans and pots like a kitchen at home), she left us some tea and coffee to use, on one of the days we found fresh homemade cookies from Burano - Very nice surprise.
It is important to stress that Luigia's apartment is right next to this one (shared wall) but we didn't feel her presence at all.
Overall, i would Recommend this place. Getting to the apartment can be tricky at first but it is in a great location, 5 minutes from piazza S. Marco and Campo S. Maria formosa.
