My friends and I enjoyed our stay here. It’s very close to the metro (Marina) and is only a 15 minute walk to La Sagrada Familia.
The only thing I would say that was surprising is that the master bedroom door/window does not block out any noise. My friends and I could hear everything going on outside during the night. I would suggest bringing ear plugs is you are a light sleeper.
But other than that, we had a great time and I highly recommend this place if you are looking for something close to major attractions or the beach.
