Lesson learned. Unfamiliar, discovered it's sketch/unsafe "Naked Vegas" quoted online "primarily vacant, rundown multi-unit apartment buildings housing low-income tenants". Due to flight, arrived after 1 a.m. Directly next door is 7-11 w/ 20+ homeless camped/fighting/wandering around/near entry gate. We were approached while trying to enter gate, felt incredibly unsafe. The fighting/noise carried through the night. Trying to fall asleep, could hear police PA telling homeless to "break it up". Mattress on a platform that rocks/teeters when you move/roll over. Exterior door in bedroom is broken, w/ pole in the track to keep it shut. Shower back up instantly w/ standing water. We left w/in 9 hrs, despite 4 day stay. Messaged host we left, to be cleaned/rented again. Conveyed reasons for exit were safety/maintenance related. Host response: cameras didn't show described events, discredited safety concerns, implying I'm dishonest? I tried to be gracious, but disappointed in host response.
