Olga's place is excellent if you plan to visit both Bilbao and around. It's super easy to take the metro and get to the city center, the trip takes around 25 to 30 minutes. If you come by car you can easily park on the street and use Olga's place as a base camp to explore the Basque coast! Sopelana beach is beautiful and just a few minutes walk away. Olga was super friendly and responsive, I absolutely recommend her flat. It has a working kitchen and a nice bathroom, plus all the basics for a cozy stay. :)
