Ongoing Spanish language course (Valencia)

Hi, my husband and I will be moving to Valencia next year around April. We are interested in finding an ongoing Spanish language course, as opposed to one that you can dip in and out of.

My worry is finding one which is catered more to backpackers. Ideally I would like to find one that progresses from Beginners through to Intermediate. It would be frustrating if the lessons start to repeat themselves to accommodate newcomers each time.

It would be greatly appreciated if you can point me in the right direction.

Thanks in advance.
