I leave mine in the shed. Chained to a wall, behind locked doors.
I use my bike daily, and taking it inside is just a pain and gets dirty fast. I used to store it in my bedroom, but after the first winter I scrapped this idea. The snow I ride in isn't what I'd call clean, and bicycle have a tendency to build it up. Take this inside and it melts everywhere.
Though honestly, I think I'd have problem sleeping at night if I had to store a 5 k$ bicycle in a shed. But then I would not use such a bike to commute daily anyways, so keeping it inside probably would not be as troublesome.
I think you need to be more precise about what you mean by "storing". Will it be used daily, or do you want long-term storage?
I ride daily-every 2 days or so, I mean somewhere to put my bike when it's not being ridden, I don't own a shed or a garage, only places to keep it are in the house, So I need a better place to put it than just leaning against a chest of drawers
