They will cheat you
Rude leasing staff, awful experience
Property Manager Responded
Loud doors that slam, weak floors, endless stomping
Awesome Staff

I don't know about their quality of the apartment but one thing I know is their pricing is fake.
Awesome home
We love Alley 24!
It's an alley. But in downtown Seattle.
