The host switched our room at the last minute (while we were in the airport waiting to fly out, less than 24 hours before check in), to a very dirty room that wasn't even listed on Air Bnb. When I asked for a partial refund, they refused, and I had to contact Air Bnb support.
I gave 2 stars because they did get us a place instead of just cancelling, but it all felt very shady and the room we ended up with was absolutely disgusting. And for them to refuse any kind of refund, when we very clearly did not get anywhere near the quality of room that we paid for, was insulting.
There's much more to this story that I'm leaving out. If you do book with this host, I hope your experience is better than ours.
