I recently stayed at the Langham Hong Kong, Tsim Sha Tsui and was not at all disappointed. The staff first and foremost the friendliest and most helpful & the location is great.
Definitely value for money and will be staying there on my next trip to Hong Kong. However I must say my stay was so pleasant I will be inclined to stay at the Langham chain wherever possible during my travels.

We found the Langham extremely good value.
It is located conveniently near the Star Ferry pier and shopping area of Nathan Street, in Kowloon.
It is more a hotel catering for businessmen than tourists and sadly has no views of the City.
That said, it is extremely comfortable and the service is excellent.
The rooms are of a good size and are very comfortable, with all amenities and luxurious touches. Our only criticism is that there was a glass window between the bathroom and the bedroom (why do hotels do that?!). Although there was a drawable blind it did not cut out the light if one needed to go to the bathroom in the middle of the night, thus waking up ones partner.
There are large comfortable, impressive, public rooms and good restaurants in the hotel.
Breakfast was included in our package and was excellent. We had dinner in the Boston restaurant and whilst the food was acceptable we found the room, which is in the basement, very dreary.
Service was excellent and the Concierge especially helpful.
We would recommend this as a very well located, luxurious, and good value hotel.

This hotel is extremely well located for shopping, dining and access to transport. The rooms are quite large and well appointed. The staff go out of their way to make your stay comfortable. Wifi was free in your room. The pool and gym area had good facilities and were easy to access.

I have stayed in the Hotel several times and each time I do it feels better. The rooms are spacious and very well decorated (specifically, but not only, the newly renovated ones). Every gadget you need is provided and worth noting is that the WiFi in the rooms is strong and stable.
Staff is very helpful and there is a multitude of them, one never has to wait more the few minutes for the desired service. The club is lavishly decorated and the b/fast, snacks and drinks in great variety and quality.
Don't just sleep in this Hotel, try the restaurants, all are excellent but my preferred is the Bostonian with its amazing selection of outstanding oysters and close to perfect Australian beef. Whine selection for French wine is good the rest could be augmented. When in a hurry or when only a snack is what you want try the Main Delly as good as it gets, almost like being 'below canal' in NY.
In summary, whether you are doing business in HK or there for pleasure, the Langham is a great place to sat, eat or stay and eat.
