Lively and efficient customer service even in the early hours of the night. When we arrived at our apartment at 2AM without a key under the mat as promised, we placed a call to Airbnb. After confirming who we were, they were able to provide us with the host's phone number so that we could call and try to get the issue resolved. We had to stay in our rental car for a few hours, but with Airbnb's consist effort, we were able to get ahold of the host. Airbnb noted the case and followed up with us throughout the issue. The even followed up and apologized the next day. Great customer service!
