Hackers Help: Locking a PAX Double Door?


I’m starting to AirBnB my Apartment and want to lock my PAX wardrobe.  It’s 39 x 93 and has two swinging doors with knobs.  I was thinking about getting something along the lines of those baby-proof cinching locks for cabinets but am hoping someone has a more elegant solution.

I don’t need it to be super secure – but just be a clear signal to renters that this is not a space they should be messing with and that it would have to be a deliberate breach of a lock for them to get in there.
