If you are looking for a nice beach place to stay, close to bilbao. Sopelana is the perfect choice. The beaches are beautiful at 20-30 minutes walking distance and the metro down the road brings you in 45 minutes to Bilbao. Iker is a great host. Even though we arrived late in the evening he waited for us to show his apartment. Throughout the week he was reachable for any questions and he gave us some tips of nice places to visit aside from sopelana and bilbao, like San Juan de Gaztelugatxe. My friends and I really enjoyed our stay!
