The stairwell always smelled like urine that was unpleasant. The worst thing that happened was the app that unlocks the doors expired two days before we were supposed to check out and we had to call the emergency number to remotely unlock the door. I finally got hold of the manager and they said that they will send someone in 15 to 20 minutes, but the person never showed up. Later they told me the person went to the wrong apartment and no one was there. There were several families standing at the stairwell trying to call the emergency number, which tells me, we were not the only one having trouble with the app. Later the management even admitted that the app must of had a problem. I think this also probably led to the urine smell in the stairwell, someone probably had to go to the bathroom when the door would not open.
