So our reservation is for six nights starting July 17th and we sent multiple messages to our host within the last week. He has a one hour response rate leading us to believe he is probably ignoring us. The Airbnb is overseas and now we're getting uncomfortable with the idea of having a host that doesn't respond to inquiries. Should I contact Airbnb support in regards to getting in touch with him on my behalf? What happens if he doesn't respond to me/Airbnb?
