Ok, this apt rocks! It's really nice and located two blocks from amazing restaurants on Parallel and Parlament. And a nice walk to the Ramblas, Gothic Quarter and The Born. Mount Juic Park is right behind it, but we didn't have time to check it out. Even the surrounding neighborhood had tons of plazas and areas to sit and have a coffee and a bite to eat. Johanna and her team stay in touch prior to the trip and make sure you know what's going on. You do have to lug your luggage up several flights of stairs, if that's an issue for you.
Barcelona is an amazing town. Avoid the Ramblas. it's a tourist trap. The Born is much cooler. Also, take a pass on the Picasso Museum. It's expensive as hell. You can see his vital work at MoMa in NYC.
