Any Bilboa recommendations?

[needhelpwiththisplease]

Just booked 4 nights and looking forward to exploring the city.
Anyone got any recommendations please?

Just got back from a 4 day trip. We did a bike tour the first morning which was good. Easy cycling. The Guggenheim took up a morning. We also went up the funicular. There was a nice public pool up there which was very quiet. Lots of food and drink. All very tasty and reasonable. Enjoy!!
