We stayed here for 2 days and we had a really good experience. When we arrived someone was coming out so I can’t say much about opening the door with their self check in method but when we got to the apartment it was simple to open it up. The place itself did smell like cigarettes, but I’m assuming it was the next door neighbors because it would fade and return. The apartment was super spacious, comfy and minutes away from the sagrada familia on foot! It was in a prime location. I would definitely go back here in the future!!
