You should stay here. Everything others have said in its praise is totally correct.
Cheapest way to get here from airport is No. 5 bus from Airport (get tickets from kiosk)to Venezia then Vaporetto no.1 from Piazzale Roma (get tickets from kiosk) to S. Angelo, and text Jacobo. He’ll take you to the flat.
Best Airbnb we’ve stayed at.
