This small guesthouse is set in one of the most picturesque fishing villages of Eastern Cantabria, overlooking a small cove sheltered by a natural harbour. Five minutes outside of pretty Castro-Urdiales, the Aisia Islares Spa will help you spend a relaxing break on this unspoilt green coastline. Spend your evening taking in the panoramic sea views from the guesthouse restaurant, which specialises in local seafood and rice recipes. You can also spoil yourself with a rejuvenating session in the on-site spa, where you can enjoy massage and beauty treatments. Surrounded by the sea, the guesthouse lies in an area popular amongst surfers and divers. For a cultural experience, the city of Bilbao is a 30-minute drive away.

Located above the sea and next to a natural harbor Islares, in one of the most beautiful corners of Biscay, and only 5 minutes from the center of Castro Urdiales.
