the router and the devices in son's apartment. I'm guessing that sweet spot will be in the garage? Placing the extender next to or very near the router will gain you nothing I'm afraid. I had the same question at first. Look for the sweet spot.

I would expect your son could chum off your internet account with the extender, but I'd wait to see the performance before canceling. He'll be using some of your band width if accessing your network/internet account, however, so depending on what your band width is you might see a degraded performance under some circumstances.

On Edit: My detached studio is about 75' from my modem and router in the house, and the signal has to go through at least 50' of interior and exterior house wall before it enters my studio. Entry to the detached (10') studio involves the signal passing through another exterior wall and traveling 20' more and through another interior wall to my devices. Presumably your attached apartment has less distance and fewer barriers and if so the TP-Link 1200 extender should adequately boost your wireless signal in my experience.
