I admire the creativity and hustle of people who manage multiple Airbnb units. This is a classic "you get what you see." It's a simple place, but really helpful to have four bedrooms with two twin beds per room. And it's convenient to have the tram nearby.
The furnishings were clean enough, but definitely on the cheap side. I laughed when I went to hang up my towel in the bathroom and the hook was a screw. I mean, it worked...
The unit next door (another Airbnb managed by the same people) was a group of 20-something guys coming in for a fun weekend. I think that's more the target than my three young kids and older parents, though we had a fine time here.
Would I stay here again if I return to Zurich? Maybe. I have no complaints. But I may look for something with more character or charm first.
