The Rex Hotel was the place where daily media briefings were held during the Vietnam War in what became known as the "5 o'clock follies". It was the favorite hotel of the military brass and it served as the mess for officers. It is still a very elegant place and a visit to the rooftop terrace both during the day and the night is a worthwhile endeavour.
The Rex Hotel was a popular haunt amongst journalists during the Vietnam War. It was once home to the daily U.S. military attaché’s press briefing which was dubbed the “Five O’Clock Follies” . The Rex, while not as modern and as upmarket as the newer hotels, still has a charm relating back to that period.
Arguably the most famous Rex Hotel in the world, thanks to its association with American servicemen during the war. You can stay here too if you're willing to shell out. It's scheduled to undergo a multimillion-dollar transformation into a 5-star hotel, so hurry before it gets too expensive.
I don't really know what's so good about this hotel, but u seem to get a lot of HO CHI MINH related travel sites mentioning this hotel time after time.
If you really want to be a tourist in Saigon, visit this place. We dint like at all, full of old tourists, kitsch atmosphere, bad drinks (but friendly staff). The building is interesting.
