It is a new hotel that is not known yet, but I imagine soon demand will ramp up. If you like quiet and minimalistic kind of hotels, this is the place to go in Beijing. Good restaurants, and excellent rooms with all the details you would like to have in it. Well designed.
Well located, close by to the major places in Beijing (Forbidden City, etc.) and on top of a subway station where you can connect with the rest of the city. Various restaurants and shopping streets are close by.
In a nut shell my wife and I spent quite some nice days and enjoyed our stay. Definitely a repeat.
