Residence 602 is a stately three-bedroom, two-and-a-half-bath condominium in one of Nob Hill's finest prewar buildings, directly across from the Fairmont, two blocks from Huntington Park and Grace Cathedral. North-facing picture windows frame Russian Hill, the Transamerica Pyramid and Bay views, and new half-inch glass mutes the sounds of the city. The kitchen, second bedroom and den open south onto the courtyard for direct afternoon sun. The craftsmanship was meant to endure. Nine-foot ceilings run through the main rooms, an original coffered ceiling with leafing and rosettes crowns the dining room, and built-in shelving flanks a wood-burning fireplace. The kitchen is large and bright, with two convection ovens and a butler's pantry, and every bath has a window. Doormen are on duty seven days a week for packages, deliveries and guests, and the building has been kept accordingly: newly modernized elevators, a restored lobby, DoorBird video entry. Garage parking is available.
