Aarhaus
Website: http://www.salsaclave.dk/index2.html - They have drop-in lessons and free dancing after the classes. They have a solid website (although not in English) and because it is nicely done, some of the information is read-able (locations) because of it.
Website: http://www.mambomania.dk/ - They may have 'mambo' in their URL name, but, their site is focused on Cuban salsa. Although they focus on rueda, they are also starting to give lessons on2.
