The apartment is well provided, with its toiletries, clean bedding, cutlery, etc. There is even an espresso machine! Also a map with useful information.
A bit of downside could be the noise of machines at nearby restaurants at night time, but I suspect that's everywhere in Venice, especially in so well located places.
IMPORTANT TIP if you need to leave your luggage in the building on your last day: when you go back to collect your bags, you have to access the building by entering a code (as you woukd have left the keys already). If by any chance someone has locked the main door from the inside, the door will not open. So put a note ON the lock so nobody does that. There is already a note at the entrance advising people not to lock the door, but they can easiky miss it. This happened to us, but thanks to Elena's great help and prompt action we managed to get in and made it on time to catch the plane! :-)
