Thats generalizing somewhat...I have rented through many 'one man band' agencies - never had a problem, there are many dishonest people on the coast now in various walks of life, think property sales/ timeshare /builders etc etc, don't knock the honest small agencys, who I am sure are trying to scrape a living and usually operate on personal recommendation. In fact I know of a recent case where the agency was S.L. didn't stop them dissappearing with deposits, rent money etc etc, an S.L. doesn't protect anyone if they leave Spain and cannot be found......
