The apartment is situated in a very convenient location, very close to a metro station and a bus stop. It was very easy to commute to any tourist attraction in Bilbao. The check-in was extremely easy, and communication with the host was instant. The apartment itself was very clean, but it seemed to be slightly smaller than it looks in the pictures. There are 4 sleeping places, two as a sofa bed, and the other two as a bunk bed hidden in a wardrobe - which is not visible in the pictures. The sofa is semi-comfortable, but you can survive a few nights easily.
Overall, we enjoyed the time spent there and recommend it to anyone :)
