I was highly disappointed with this booking. I have used airbnb many times and have never experienced this behavior from a host. We had a weekend planned to go to Bilbao for a concert with 5 girlfriends. We booked this airbnb because it seemed perfect. Because of covid, the concert was cancelled a week prior and we were unable to cancel our booking, we even tried talking with the host to see if we could move it to the new concert date in April, the host agreed but doubled the price, and blamed it on airbnb's pricing methods. The host was unable to cooperate with us with this so instead of cancelling and losing our money we decided to continue with our trip sans concert. I took a train from Madrid to Bilbao (5hrs), 30 minutes before our arrival, the host privately sends me a WhatsApp asking for a 'fianza' or a type of deposit of 150euros that we have to pay outside of the airbnb platform. I felt really uncomfortable about this because it was not mentioned in the ad when I booked the airbnb for us. I am happy to pay a deposit but would have happily agreed to it had it been in the booking info prior to the booking approval, as well as paying the fee through the Airbnb platform not some random bank's external link. Regardless I felt really uncomfortable with this last minute news, the host said if it wasn't paid they would cancel the booking. I told my group of friends, and one of them who's Spanish is better than mine talked to the host. I realized she might have been rude to the host, but I felt taken advantage of and this is outside of Airbnbs policies. I contacted Airbnb and they said I was in the right, the host proceeded to cancel the booking, and I got my money refunded. Luckily we were able to find a hostal nearby for our weekend. I was very disappointed by this experience, but impressed by Airbnb customer service and care.
