First of all, Nina is lovely and provides you with all the necessary info in order to have a pleasant stay.
The apartment is just as described and looks exactly like in the pictures. The kitchen is pretty well equipped (we found everything needed to prepare breakfast).
The proximity of San Marco Square, intimacy, and quietness even though it is located in such a crowded area, the fact that we had no issues with the shower, heating, or anything else was excellent. It was my third stay in an apartment in Venice and the noise 'issue' is quite common, so I will not consider it a minus for this apartment.
All in all, I'd book this apartment again without hesitation.
Thank you, Nina!
