Concierge.com's insider take:

The landmark Hotel Saigon Morin has stood since 1901 on the banks of the Perfume River through war, flood, and typhoon. Remodeled a decade ago and expanded last year, the practical-minded 184-room hotel offers easy access to the Citadel from Truong Tien Bridge, which is just across Le Loi Street. Supersized second-floor rooms in the original wing have 13-foot ceilings and Continental-style furnishings such as cabriole chairs, beds with padded headboards, and thick drapes (though they unfortunately don't quite muffle the traffic noise outside). The quietest quarters, rooms 140–168, are in the rear of the hotel. A peaceful inner courtyard holds a kidney-shaped swimming pool and a tree-shaded café with Parisian-style wrought iron furniture. Hotel service is attentive, from the rose-petal-strewing housekeepers to maintenance workers who arrive moments after a glitch is reported. The four-star amenities also include a tour service, currency exchange, beauty salon, and free lobby Wi-Fi. And breakfast might be the longest buffet in Vietnam: Platters of mango and pomelo, croissants and cheese, and banh khoai (steamed rice paper pancakes) stretch at least 30 yards.
