This is part of the frontage of the AC Hotel Cordoba Palacio, where we stayed for a night on our way up to Bilbao. The glass you can see is one of the sides of the very nice restaurant in which we had dinner.
It's a striking hotel in that it's swathed in a gigantic rust-coloured screen, which looks a little hideous to be honest. But the hotel itself is extremely comfortable and we certainly enjoyed our one-night stopover!
