We had a wonderful time in Sopelana, at Maria's appartment. she is really nice and helpfull, offered us a lot of suggestions, such as taking the metro to Bilbao, going to Getxo, making a wonderful Tour along the beaches. The beach is nearby, a trip by foot down, is rather quiet, friendly for children, with high waves and beautyful sunsets.
The appartment has everything, nice beds, and stays rather cool. Thanks Maria and family for letting us stay at your place!
