Marco met us on time and gave us a binder with good information. The apartment is cozy and clean. It's on a cul de sac and very quiet although it's only steps away from San Marco.
The only downside was that on a hot night, the air conditioning unit hardly made a difference as the window had to stay open to vent the hot air and we hardly got any sleep with 32 C.
Overall we had a wonderful time, and would definitely come back if we ever were to visit Venice again!
