I stayed for one night, as my flight into Da Nang arrived late in the evening. Taxi ride to the hotel was required, as the hotel forgot to send the car that had been pre-arranged.
They made up for this by upgrading me to a suite.
Sky bar is pleasant, food is generally decent and tasty, and staff are generally polite.
Not sure about the local area, as I didn't stay long enough here. Definitely fine for an overnight stop.
Some work to do on cleanliness and finesse - bath mat was dirty, one of the bath towels smelt like it had not been dried properly before being put into the room, and the bathroom generally was not as clean as I would expect (mouldy grout etc)
