In the US the rent quoted is the total for the apartment or house listed.
I hope you plan to see the apartment in person before signing any contracts on it.
If you have never rented before you may want to consider looking for the cheapest 1 BR you can find. You might have trouble finding/keeping a roommate. You might have trouble qualifying for a more expensive apartment (like 2BR) on your own & if the roommate takes off, you are still obligated to pay the full rent.
