There were literally no hotel rooms left in Bilbao so I tried Airbnb for the first time. It was perfect. I arrived very late, about 11pm, and Ales was there to greet me. The flat was beautifully clean and in a very elegant area very close to the hanging bridge and the excellent metro. Good supply of coffee chocolate and little cakes were waiting for me. The only problem was the rain. Bring an umbrella at least in April!
