There is a thread on EOS if you search on insurance. I also typed "Spanish Contents Insurance" into Google and got a few alternatives. In the absence of any recommendations I narrowed it down to Intasure or Schofields as they seemed popular; UK based, with policies written in English and underwritten by reputable companies. I accept this is not very scientific, but I need a product that covers contents and limited building (sanitaryware etc.) also providing public liability and accidental damage plus cover for renting. I opted for Intasure in the end, but it depends on what you want from your policy - both are worth a look, but don't just buy on price as it can prove expensive when it comes to making a claim. Hope this helps.
