Apartment was near ospedale ferry stop. Wish we had stayed near San Marco. But this wasn't bad at all. If you want to go to Murano and Burano islands this is very convenient on the 12 line. Highly recommend doing that.
Apartment was big and plenty of space for us. Stairwell was dark at night but doable. Very clean and the hosts were easy to communicate with. No complaints here. I'd stay there again if I went back.
