Despite having paid in full through Airbnb, unless you bring a credit card and pay another £50 refundable deposit, you won’t be allowed to stay. Debit card or cash are not accepted. They will literally refuse you entry. The only suggestion manager had was that I either get a friend to bring a credit card or pop back home to get it otherwise there was nothing they could do.
I received 8 emails from Locke and Airbnb after I booked and none of them mentioned this vital detail. To say that I had agreed to their Ts&Cs when I booked is just not good enough.
