Mercedes Cortez' apartment is located in Vice Point, Vice City, near Leaf Links. It is also just across the street from the Links View Apartment.
The apartment appears in the Grand Theft Auto: Vice City mission Love Juice when Tommy Vercetti collects Mercedes from the apartment. Following this mission, the apartment makes no further appearances in the storyline.
The apartment appears in Grand Theft Auto: Vice City Stories but plays no role in the storyline. It is unknown if Mercedes is living here at this time as she does not appear in the game. A Stinger can be found parked here.
