Upon arrival, Kristina buzzed us into the building. The instructions say to find a key hidden in a community fire extinguisher case. Ben the host warned us not to disclose our Airbnb status or visit the leasing office. With only one key fob for the unit and building, it was unsuitable for groups. Our stay began well, with Ben even allowing packages to be delivered under Kristina's name. However, the host's girlfriend entered the unit without permission and left a package, which shocked me, especially with my small dog in the unit. I expressed my discomfort and that I could not stay even one more night with how comfortable they are entering my rental unit but Ben reacted angrily that I wanted a refund for the remaining nights and that he would come move me out himself. I packed as fast as I could as I could. Within 5 minutes he was in the unit yelling at me. I had Airbnb on speaker phone trying to get help. This is not a safe environment.
