Overall, it was quite disappointing. I've always had a positive impression of Da Nang, but my experience at this hotel didn't live up to expectations.
The rooms were quite stuffy, and the soundproofing between rooms was very poor. The only positive point was the city center view. However, what I found unsatisfactory was that guests weren't allowed to go to the top floor to watch the fireworks, even though it's a common area of the hotel. Guests who wanted to watch had to pay a very high extra fee because that area was used for private business on the day of the fireworks.
The room price wasn't cheap, and I expected a better experience. Unfortunately, this was a less than ideal experience and didn't leave much of an impression.
