Super modern unit and clean. However, we initially had a broken (nonfunctional) light switch in the bathroom. This was quickly fixed after bringing it to host's attention, though nobody wants to see exposed/broken wires in a bathroom upon check-in.
The bigger issue was entry and exit into the courtyard area ... which is before the actual front door of the unit itself. For our entire stay, our keys would not open the front door. This was casually acknowledged upon check-in by the agent (it's a third-party property manager from what I can tell). She basically told us we should use the back entry. This is a rather long (and dark at night) additional walk around the corner. Of course, one set of our keys wasn't working well with that door either. As we were leaving, the front lock was supposedly getting changed but we get the sense this is an ongoing issue from discussion with others.
The location is good, but it's a bit of a walk from the train station if you're dragging bags. Several good vaporetto stops nearby though, including one of the last Alilaguna stops before the airport.
All in all, the unit is super nice and everything went well enough. However, it was the first time we've ever experienced any type of ongoing inconvenience like the lock situation. Not a deal breaker or massive problem, but it would have been a much bigger issue had the 72-year-old woman in our party been there on her own.
