Positive: Localisation, kindness of the host'employee, good beds and enough linen
Neutral: quite cheap materials, appartement is dark and not sunny as shown in the pictures, 2 stairs, so this can be an issue for those having problems with stairs
Negative: air conditionning in each room but very noisy, you have to get the water out of the tank after a few hours (issue at night) and leaking in one of the room (not great with the electricity plug next to it!)
General comment: housing in Venice is expensive and of poor quality except if you spend a lot of money. Here the issue is really with the dangerous and noisy air conditionning
