500 Republica/Legends

Probably the most exclusive tower block in the entire galaxy, 500 Republica is located in the Senate District and is home to many wealthy citizens including senators and successful businessmen. During his time as Supreme Chancellor, Palpatine had a luxurious apartment suite in undisclosed location of the tower. Near the very end of the Clone Wars, Mace Windu, and a squad of Clone troopers discovered a passageway in the sub-basements of 500 Republica that led to a building in the abandoned Industrial District.

Dispite this, when the Confederacy Army lead by General Grievous attacked the capital world of the Republic, they knew exactly where to go for their target. Grievous' plot to capture Palpatine from his home was foiled by the Jedi who had been assigned to protect the Chancellor.

On the same day as the Separatist's attack on Coruscant, Republic Intelligence had discovered the shocking truth that Darth Sidious was operating right from the very heart of the Republic, and was traced back to 500 Republica.
