My first (and last) experience with airbnb was trying to book a space. The listing was reasonably priced and perfect for my travel dates. My reservation request was declined. I assumed that someone else has requested the space before me. Turns out the listing was reposted that day for $60 more a night. I was curious so posted another request for the reservation. The request was denied. I am betting the price goes up again today.
Contacted airbnb and they said they can't control it and have no repercussions for hosts that raise their prices in this manner. Good luck with that business!
The host, by the way, is "Shannon" in Las Vegas. I'd suggest you stay away.
