We had a fairly miserable trip from the U.S. to Spain - a delayed connecting flight caused us to miss a flight with ensuing rebooking on a different route; lost luggage; having to rent a car to get from Madrid to Bilbao due to being a day late, etc., etc., etc.
Throughout it all, JJ was nothing but considerate, gracious, and supportive. He went well out of his way to accommodate our late arrival in Bilbao and turned what so far had been a fairly miserable trip into a wonderful Bilbao experience.
Highly, highly recommend. His place is in a superb location, clean, and charming. When we come back to Bilbao, we will definitely be staying here again if at all possible. Great place and great host.
And be sure to try the bollo mantequilla (a Bilbao specialty) from the bakery up the street. JJ suggestion.
