@zazie -- Sabrina !!! Yes, you are correct. It was an amazing experience. I arrived there with less than an hour before closing, as I had been in meetings all day. They suggested I come back as I had so little time, but I was flying out the next morning so I had no choice -- then or not. But what I found is that nobody else enters La Pedrera an hour before closing, which means that I had the rooftop nearly all to myself! :)
