The safest place would be multiple paper wallets, and make sure you make AT LEAST 3 copies of each. Store them in places around your house you will remember.
No one can touch them that way.
Wouldn't someone be able to steal your coins if they robbed your house? Or if they simply found one while being a house guest of yours?
If has knowledge about BTC, it will happen but the chances are less. Anyway, there are many safe places in home like refrigerator.

The refrigerator is a common hiding spot. If I was going to rob a house it would be the first place I would look.
Places criminals look for hidden valuables:
Go get the money mutherfuckers
In an envelope taped to the bottom of a kitchen shelf - check under all drawers
In a watertight plastic bottle or jar in the tank on the back of the toilet
In an envelope at the bottom of a kids toybox
In a plastic baggie in the freezer
Inside of an old sock in the bottom of the sock drawer
In an empty medicine bottle in the bathroom - take all medicine - you might find something to get you high later
In the pocket of shirts in the closet
In a folder in the filing cabinet
In an envelope taped to the bottom of the cat’s litter box and in the litter
In an envelope taped to the back of a wall decoration
In between several pages in a random book or two on the bookshelf - throw the books to the floor shit will fall out
Buried in a jar in the back yard - look for dirt that has recently been turned over or has nothing growing on it.
In a tool box in the garage
Underneath a potted plant (or even buried in a small jar in the soil)
In an envelope taped to the bottom of a dresser drawer - check all drawers top and bottom
Inside of a big coffee cup in the back of a cupboard
Inside the Christmas decoration box - most common place - check all boxes in the top of closets especially if you "own" the house for a few hours (out of town, you shot them, at work, etc.)
Inside of an empty bottle of beer in the back of the fridge with the cap seemingly
in place (smash it to get the cash)
In a plastic baggie inside of a flour or coffee container
In an envelope inside of a DVD case
It looks like a lot of work but you can do this whole list in one hour before the bitch knows what hit him
