In hindsight we'd stayed in Venice rather than mestre as it was a pain in the proverbial to head back to the apartment. The photos are representative of the room and overall is good value. Having said that, the mattress on the bed was so hard that I'm still in pain 2 days later. Back pain isn't nice. The room was clean but the shower needed a bit of a good going over. The owners need to explain how to use the keys to open doors as the noise from adjacent apartments was unwelcome as the other occupants spent a few minutes each time trying to open the doors.
Overall the room was good value but if you don't like a hard mattress and don't want the magic of Venice being broken by inconvenient travel to and from the apartment then don't stay here. If you're staying in mestre because you want to be in mestre then perfectly located and good value.
