Travelled with our 3 year old. Ideal set up for our 4 day stay. Accommodation superb and hosts were both extremely helpful. Would highly recommend. Walkable to the Guggenheim and excellent transport links in and out of the city. Bilbao was a fabulous city lots to do with a toddler. On top of the museums, and good shopping/food. We found Excellent swimming pools, beach’s and parks as well as watching red bull high diving.
