We had everything we needed at Luigia's place. The apartment is in a very convenient location, only a few minutes walk to San Marco Square. We also really appreciated a supermarket less than 50m from the door.
Luigia lives in the next door apartment which meant there was the reassurance of knowing that she was there if anything was needed but also the apartment is completely separate and private. The kitchen was well equipped for guests who like to self-cater, the bed was large and comfortable and the apartment itself was spacious, light-filled and airy.
Luigia was a very thoughtful host, as soon as we had made the booking she sent us hand-drawn maps of how to get to her place from the San Zaccharia/San Marco area and also from the Ospendale vaporetto stops. These were invaluable during our week-long stay as the Venice streets can be a bit confusing and sometimes online maps aren't as useful in Venice as they are in other places. She also did a pictorial map of useful local places (chemist, good pasta, sweets etc) that we might need.
We also were given two sets of keys (something we discovered does not always happen with Air Bnb's) which was really needed as one of us was attending a conference for part of the time and so we weren't coming home at the same time.
If I were visiting Venice again, I would not hesitate to book this apartment.
