Do you have to bring your own towel, washcloth, and soap for showering?
you can rent a towel, but bring the others. you can buy them for cheap near the hostel.
I'm not exactly sure. I didn't have them with me. I don't think they provided them. Maybe email the hostel :) Enjoy Venice!
Bad place. Change location in you want join Venezia! Imbarcadero is a dirty place. The manager is syrian!
