Monthly Storage options?

Hello all,
Does anyone know of a "StorageMart" type company in Ha Noi? Where you can put your stuff in a locker, take the key, come back later.  I found one called King, but its a big hike from Hoan Kiem.  Are there any others?
Thanks!
Rob

Not sure if this is too expensive or not but check out the link. Also read that the Hanoi train station have lockers but not sure if that's too far for you.

Thanks. I will check it out.
I was not very clear - I am looking for a place to put a larger number of boxes and bags.  The contents of a small apartment (no furniture).

Maybe check out KingKho Storage.. it's a self-storage company with international management I believe.. I rent a unit there myself since a couple of months.. everything worked well so far.. rented a M unit with a door, like a 2-3sqm walk-in closet.. 

clean facility bright and good service..  the manager lady there speaks English, and she knew what she was talking about..
