I always wanted the double story Miami Apartment... I'll try and post pictures of mine! Also, if you're wondering what happened to our huge collection, we didn't want them anymore (WHY DID I SAY THAT?!) and Mum gave them away. But... we still have the battery covers XD We used to lose them all the time.
