Lombard is a relatively busy street which is in the north part of the city, near the Golden Gate Bridge. The neighborhoods are the Marina, located on one of the Bay's marinas, and Pacific Heights with stately mansions and steep hills. Mrs. Doubtfire was filmed in Pacific Heights. This area is very convenient to the Golden Gate Bridge, where you can walk, bike, or drive to scenic Sausalito and beautiful Marin County. Since availability can be tight, I have recommended several hotels in the area, even though some have higher pricing.
Weekends are much busier.
People at the reception were kind and helpful. All hotel rooms are non-smoking. The complimentary continental breakfast also included very good English tea, juice, coffee, muffins, bagels, etc. We greatly enjoyed our brief stay and, should we ever return to San Francisco, we will stay at the Marina Inn again. This is not in the Marina area, but located in the general vicinity.
