This Airbnb was in a great location! The host was really really helpful when I left my luggage on the train, he communicated and is having it sent to me in the states. Also the Airbnb was really nicely laid out. And there wasn’t much noise from the street even though it was centrally located. Close to Plaza Cataluña. It does have an alarm system so make sure you understand how it works and if someone stays in the apartment while the other goes out makes sure they have a set of keys in case the alarm goes off.
