We were a large group visiting Bilbao for the first time and Serafin's apartment was perfect for our visit. The beds are comfy, the sofa bed is great & there was enough space for all of us. The location was ideal for exploring the Old Town, walking into the centre, having a few beers by the river & getting the metro out to the beach. We did eat out every day so can't comment on cooking/dining in, but the dining table is a decent size for at least 6. Thanks for having us!
