Host is offering only a partial refund after the house was infested with yellow jackets [USA]
We got to our destination and found a bedroom was infested with yellow jackets. The host showed no concern about it "these things happen" and said he would address it on wednesday. We arrived on Saturday and were to check out on tuesday. Now he's offering a partial refund, 800 out of 1300. He says "we have to pay Airbnb for their portion" and for a cleaning fee. What steps would you suggest for pursuing a full refund?
