We got to Barcelona a few hours early so we just waited at a restaurant in front of the building. The process of entering the building and apartment might be a bit much for the technically challenged but it was quite impressive–the doors open with one swipe on your app if you have your phone on the correct settings.
Anyway, the apartment was very clean and neat when we got there. The location was great as you are around shops and restaurants. All in all, I highly recommend this apartment if you’re ever in Barcelona.
