A person is taking a selfie in a mirror in what appears to be a gym changing room or restroom. The person has dyed blue hair and a tattoo on their left arm. They are wearing a black t-shirt and maroon leggings. They are holding a smartphone in their right hand to take the photo. Behind the person and reflected in the mirror are light-colored lockers. To the right of the mirror is a sink with a stainless steel faucet. The walls are dark gray. Given the presence of signage in Spanish (the emergency exit sign with "Salida" above the arrow) and the general architectural style, it's plausible the location is in Gijón/Xixón, Spain, as requested. However, without more distinctive regional characteristics, this cannot be confirmed with certainty.
