Just as you enter the main area of El Cotillo, on the right hand side of the road of Calle Gran Canaria is a little bar with a big screen T.V. playing continuously called Bar Piedra Playa. The coffee is weak and the danishes come from a plastic bag, but what this bar does have that appears to be better than anywhere else in El Cotillo is excellent free wifi. Fastest I have measured yet.
Service is also fast and friendly.
