Clean, has an elevator, and is close enough to the sagrada familia that you can walk there, catch a cab or hop on the metro. The restaurant downstairs is also great! The room with the bunk beds is very small and i would say is only suitable for kids but you can always remove the mattresses and put them in the living room. There's only one shower so it was a bit tight, but worked for what we needed. If you split between a group its very affordable per night for Barcelona!
