Most commercial networks systems have the ability to detect rogue access points by analysing the radio spectrum, and hiding the SSID will not avoid detection once traffic starts flowing to it.
And they can triangulate the position of the rogue AP.
Interesting about hiding SSIDs, I never knew why that option existed. I'm here on Erasmus so I don't want to risk too much by knowingly breaking rules... them triangulating it to my room and starting a legal case or something sounds real scary.
Also, connecting an access point that doesn't broadcast its SSID has another side effect: all devices configured to connected to it will periodically broadcast a signal to search for that hidden AP instead, so it makes you even easier to track down anywhere else.
That's assuming they're actively looking. Hiding your SSID is more to prevent someone from getting suspicious and calling out the ISP.
