I guess star rating systems are based on the location's other hotels? If yes, this hotel is on the borderline between and 3 and 4 stars, closer to the 3.
I think the single best quality about the place is the location, it's at the heart of Nimman district. The rooms are spacious and the interior itself is fairly clean and new. Liked the cute moose design elements throughout, the rooftop is decent but not a lot of ppl go there I think and the pizza served by them was not thaf great.
Now for the other lacking parts: first the gym is a joke ( one rack of dumbells, a bench, and a couple running machines all cramped up inside), the breakfast is not horrible but subpar for a 4 star if you asked me. There is almost no noise cancelling between the rooms, only a single elevator for hotel this size, little tiny ants here and there, and thats it. Definitely caters to the Chinese crowd so theres a lot of them, but cant blame them.
If youre looking for a Nimman hotel with a good location and modern interior I think it could be a decent choice if the price is right. But definitely at the lower end of the 4 star spectrum, I prob will try another before I visit again.
