This place was an ABSOLUTE GEM. My Wife and I stayed in the top floor loft with the outdoor bath tub and I cannot recommend enough. Such a great value for the money, it was HUGE, super clean, and right in the middle of most things you want to do in Da Nang. We came from a beach resort in Hoi An, so being near the beach wasn't important to us, but even that is a very short grab ride.
The staff are wonderful and available 24/7 in the small cafe downstairs where reception is also located and they can either help you with everything or give you advice about how to get help. My wife got sick for about 36 hours while we were there (through adventurous eating NOT recommended by the hotel, but through my own findings so I won't share the place) and she was so glad that we were at such a nice place. While she stayed in the room, I was able to explore the city more and enjoy the rooftop pool, which is especially wondrous at night. When I was there in May '22 I was literally the only person up there each time.
Bottom line: highest recommendation, I imagine their basic rooms are amazing bargains but endorse the higher-end rooms as what you get for your dollar/dong is without peer in my travels.
