Excellent stay! The king room was exceptionally clean, and the staff was friendly, professional, and available 24/7. The location is perfect, walking distance to Powell and Montgomery BART stations, two blocks from the California & Grant trolley stop, and directly across from the Chinatown Dragon Gate. Can’t wait to visit The City and stay here again in September!
