Haha, oh yeah we now have a "trastero" as well and while you think this big storage room would not be filled up that quickly, it's already half full! Granted, old beds and matrasses add up but it's good to not have to look to suitcases and boxes inside the house anymore.
I totally foresee this storage room to be filled with things we "may need" soon as well though, and then we forget about them or don't know where we left it. I'm still looking for a few items since moving, while I searched through every possible box several times now.
Weird!
