Raj's Apartment, 3D, or the Raj Mahal, is where Raj previously lived. It is a small apartment, with one bedroom, in a 67-year-old building (built 1951) that used to be a watch factory (in "The Bad Fish Paradigm", Sheldon worries about the residual radium from the manufacture of radioactive luminous dials).
In "The Nerdvana Annihilation", Raj said, "The guy who lives next to me is always like, 'I have a Jacuzzi on my balcony, I have a Jacuzzi on my balcony.' But wait until I tell him I've got a time machine on my balcony." In "The Griffin Equivalency", a barbecue can be seen through the door next to the entrance, which might be on the referenced balcony.
Priya stayed here when she was visiting and dating Leonard. Leonard even moved in switching places with Raj when it looked this he and Priya were going to move in together. She announced she was going back to India by the end of the season.
Penny has been there twice: once at the end of their "date" and once after she drops Leonard off at the airport to check on Raj.
In season 10, he moved out his apartment in "The Escape Hatch Identification". Since he cut himself off his from parent's financial support in "The Allowance Evaporation", he can no longer afford to live there anymore and his salary from Caltech is not helping him with it due to his other expenses.
