Hi,

I'm looking for 3-10 m³ of storage place, in Basel or near to. Everything I could find is quite expensive. Could you recommend something cheaper?

Thanks!

Define expensive, and define cheap please.

The one I know of that is quite reasonable for self-storage is Zebrabox, they have a number of places throughout CH, including Basel.

If you are using a moving company, I've found that adding on storage costs to the move are often not prohibitively expensive, as the company has storage facitilties and easier than using a middleman.

Other than that, find a farmer, and see if he'll negotiate storing your stuff in his barn.
