NOTE: I've used The Boardwalk and Carousel sets from the Store. The game will not replace the objects, so the rabbitholes will be missing and the look will radically get worse. ¡WARNING! If you don't install the CC the world will lose all its playability and charm. *All the used objects are included except the Arboretum, the Gypsy Wagon and the Bistro Rabbithole Rugs, get them HERE ('Misty_BarcelonaRHrug.>'). You can installed it all together by just installing the CCmerged_Barcelona file, or intall the different files separately: rar file which includes all the needed CC. To get the CC to show up, you have to download the files apart. (The world file is checked with Sims 3 Pack Cleaner). This means no undesired CC will be installed if you don't download it.
PLUS: The world includes recolors and custom lightning files.
