We just returned from 3 nights in the centrally located apartment. Check-in was pretty easy as we were given a code for the building and lock box code for the key. The apartment is nice, very basic which was fine for us. The building was quiet and definitely go to the cafe right next to it for breakfast or lunch! I know other reviews mentioned this but there is a menu listed for costs of things including coffee pods so it was unclear whether the 4 pods provided and the bottle of water were included or not- some clarity would be helpful. All in all it was a great place to stay in Barcelona.
