La Pedrera was built as an apartment complex, it is one of Gaudi's earlier works so the living quarters themselves are not that decorative or interesting but the rest of the building is. When you begin your tour (which you must have a timed entry ticket) you take an elevator to the roof and tour downward from there.
When you descend into the attic you are greeted with vaulted ceilings that create a really open area in which light enters in some places and casts shadows in others that leaves every corner of the space unique. The attic houses a sort of museum of artifacts of other Gaudi works. The audio tour doesn't seem worth it because most things have explanations, and the videos playing are closed captioned.
Again like I said, once you leave the attic you go through some of the living spaces. I think there are 4 levels but you can only explore 1 and its not that thrilling. The architecture looks like anyone could have designed it and there is no specially designed Gaudi furniture. I suggest skipping the audio. See the amazing roof and attic but spend much more time at Casa Batllo a few blocks down the street!
