Any decent/cheapish hotels or apartments in San Antonio (Ibiza)?

me and my friends are eighteen soon and we're looking for places to go on our first holiday next year. so far we've looked at san antonio, Ayia Napa and malia. we've got our ideas from bbc3's tv show "sun, sex and suspicious parents." but we're finding it hard to find a cheapish hotel/apartment which is still decent. the ones on the tv show look quite nice. so if anyone knows any hotels or apartments which are quite goood let me know please :) ... and if you know of any in malia and napa would help to xxxxxxxxxxxxxx
