The San Francisco apartment of Admiral James T. Kirk in the 2280s, filled with antiques, where McCoy delivers a birthday present and Sarek later comes in search of his son's katra.
Kirk's apartment in San Francisco appears in Star Trek II: The Wrath of Khan and Star Trek III: The Search for Spock. Overlooking the bay, it is decorated with the admiral's collection of antiques, including old firearms, ship models and clocks.
In the first film Leonard McCoy calls on Kirk's birthday with a bottle of illegal Romulan ale and a pair of old-fashioned spectacles, and bluntly tells his friend to get his command back before he turns into part of the collection.
In the second film Kirk, Sulu, Chekov and Uhura gather there after the Enterprise's return, drinking to absent friends. Sarek arrives, accuses Kirk of abandoning Spock on Genesis and melds with him, only to find that Spock's katra is not there; a review of the engine room recordings then reveals that McCoy carries it.
