Knowing whether or not I can connect internet via coax cable.

I'm moving into a new apartment in Philadelphia with my current modem/router. I am an existing Xfinity customer and I want to know if I can connect to my service at the new unit with my current setup. I currently connect to the internet via a coax cable, but I am not sure if my new apartment has a coax input. This may be a silly question since I'm not sure if every unit in the city has a coax input, but I was wondering if I can contact Xfinity to know the type of internet (cable, fiber optic, etc.) that my unit offers. They did confirm that internet is available at the unit, but I wanted to know if I could connect via coax cable connection.
