We really enjoyed staying in the apartment in old town close to the cathedral. It was large, clean, well appointed and quiet. The bed was huge and very comfortable. It was easy access to the tram, buses and metro. Great restaurants are nearby like Cafe Bar Bilbao. There was also a grocery store about a block away. The large market was only about 2 blocks away. Wonderful shopping and people watching in old town near the apartment.
We would definitely consider staying here again on a future trip to Bilbao.
