We had first spent two days at a hotel in central Bilbao, which was great to explore the museums and the old town. However, Portugalete really charmed us. The apartment was a perfect location to explore the area. Excellent spot for great pintxos almost on the doorstep (along the river stretch was great), the bridge was 5 minutes and from the other side we did a beautiful walk along the coast. We were unfortunate with the weather that day but even then we loved it. Getxo is also worth a visit.
The apartment was lovely and sparkling clean. The beds were very comfy and everything was available. Can highly recommend the area and this place.
