My place is good for couples and solo adventurers.
Luz Hotel is located in the neighborhood that borders Tenderloin and Knob Hill. The terms "Tenderloin Heights" and "The Tendernob" refer to the area around the indefinite boundary between the Upper Tenderloin and Lower Nob Hill. You'll be at Geary St that's fine. The Tenderloin is more Ellis, Eddy, Golden Gate and Turk streets. Don't worry about it, and really, Geary all the way in both directions isn't bad
