Nikko hotels tend to be very well maintained, as was this one. Focus on details means very unlikely to encounter complaints about the room. The building itself seems getting old, but actual rooms are all fine. Location is good ... though a bit less so than those right on RenMin Road. That's because 2 blocks behind the hotel are the railroad tracks, so along the tracks the establishments get a bit low end, so one is unlikely to find food or other establishments where a tourist or businessperson would want to enter. That said, going forward from the hotel entrance you go right to the heart of the city.
Net, as long as the rates stay ~US$15 less than other 4 star chains, it's a good deal to stay here, even if location is slightly less convenient than right on Renmin Lu.
