Alex was undoubtedly the best host among all the AirBnB's in Spain. He is warm and super friendly. The size of the room was apt for my wife and I to have a comfortable stay. It is clean, cute and very airy. We enjoyed day and night views of the CaixaForum which is located opposite the apartment. Contrary to the earlier reviews, we did not find the noise to be a issue even on the weekend. Would definitely recommend Alex's place for a short stay in BcN.
