Forget about sleeping if you are staying in this place. Neighborhood is shady & loud. The walls & ceilings are thin. Upstairs neighbors were loud & drunk. And even if they were not, you will still hear anything. They would walk to the bathroom in them middle of the night and you would hear it. And I am a deep sleeper. Do yourself a favor and book a newer building if you want to enjoy your visit. It was a big mistake I made.
Location wise, I thought it would be a nice one because it was 10 min walk to La Rambla, but you have to walk in a very shady street to get there, so not worth it.
The elevator is extremely small, and it is after one flight of stairs. So getting your luggage in & out of the apartment will be hassle.
The only good thing about the apartment was their fast respond time & daily cleaning.
