The apartment was cute and well furnished. It is very close to St. Mark's, but is still out of the main tourist area (a few tourists groups will come by), so it is relatively quiet. The only thing Elisabetta was working on when we left was switching out the locks - the floor of the apartment is split into two units, and you can be locked out of the floor (there is one door to access the floor of the building that leads to a hallway to the two apartment units) by the other apartment if they lock it with their key (this unfortunately, happened to us, but we were able to wake the other apartment to unlock the door). When we told Elisabetta what had happened, she was very responsive at 8am, and was on her way to the unit shortly there after.
The apartment has a small but functional kitchen, a decent sized bathroom with a nice enclosed shower that never ran out of hot water, and thankfully two A/C units, which we needed after exploring Venice at the end of the day. I fully recommend staying at Elisabetta's, and will be sure to stay here if I am in Venice again.
