Rocios apartment is great value for the size and location. It was clean, and spacious. Communication with Rocio was good, and her assistant Xavi checked us in. Xavi was super friendly, and gracious when I had some issues with my phone and checked in unexpectedly. As stated in other reviews the building is loud. But that's typical for these sorts of buildings and won't surprise anyone that has travelled in Europe. I'd suggest earplugs for sleeping if that's a concern for you. We got used to it after the first night. Location is great. It's easy to catch a metro to any Barcelona landmark.
