This hotel also goes by the name of Shangri La Saigon Hotel. It appears to be a fairly typical hotel for District 1, Ho Chi Minh. It should be fine to bring girls back. Make your reservation for 2 people, and then they cannot try to charge you for an extra person later.
For a cheaper hotel option, that I know is girl friendly, I would recommend Hotel Royal, 5 Nguyen Van Trang, District 1, Ho Chi Minh. I've had girls stay with me here before, and it's never been a problem. The night manager has been working there for years, be friendly with him when you come and go. The place is clean and a good location, and my only complaint is the hard beds, which you will find at nearly every hotel in Vietnam. This is why I prefer renting apartments on Airbnb.
Hi Logan, thanks for your time and help. I want to try the best things HCM can offer! And also some tourist places too... my plan is visit tourist places during the day time and having fun in evening at night time
You can try the Myst Hotel on Dong Khoi street in Ho Chi Minh. It's one of the more unique hotels in District 1 and girl friendly. My Malaysian friend went to this hotel a few days ago, and his Vietnamese girlfriend stayed with him for 3 days. And it's walking distance to most of the nightlife areas.
