I was only there for a day( stopped off as part of a cruise) so I’m hardly an expert on the place.
Much preferred it to Gijon, Corunna or Santander. Some great little bars and cafes but don’t expect anyone to speak English because they don’t.
It’s a huge city and the area near the port has some lovely villas, never stopped in that area but it would be worth a butchers if you’re there for 5 days.
