Great location for the price! Walking distance from the train (and bus) station, close to a vaporetto station as well. Yes, the ceilings are low, but we are 5'5 and 5'8 and it didn't bother us. You shouldn't be spending much time there anyway- you are in Venice!
Marcelo met us near the hat shop and showed us how to unlock doors, etc. A/C, fridge, microwave, cooktop. Everything functions properly.
