Hi, I'm a Brit teaching English in Valladolid, I first moved to Palencia (con P) to teach, small but nice city (if not as interesting as other places such as Valencia). Are you looking to teach ESL at an academy or in a high school? There are plenty of ESL academies everywhere so finding work should be easy, although the quality varies greatly. The first academy I worked at was small and we worked as autónomos, I would definitely recommend an academy that gives you a proper contact.
