I believe that Telefonica Es (movistar), the government owned phone company, is the only one allowed to install a land line in Spain. Telefonica is good but expensive for broadband. You need to organize line connection then research broadband companies to find the best deal (cost, speed etc.) in the area you are going to. Another Company which I know named Telitec. Telitec has a great service and package. It has Best quality service and products at very best prices.
