The company I work for recently had a conference there and boy was that an experience:

a) Check-in - I checked in later than everybody else and I still had problems. The receptionist couldn't find my reservation and asked me for my passport. When I showed it to her she said she still couldn't find it. The huge surprise was when she asked me what was my name in English which I replied, it is in English! Then she asked me what company I worked for. I told her and she said that company doesn't have any reservation either. In which case I got very upset as I walked to a nearby chaperone from the company conference borrowed the signed and pointed at the logo on it. Would you imagine that after 300+ people have already checked-in and they still don't know which company? Some would have thought that they may just have gotten used to the name by then. Apparently quite a few of the conference delegates had the same problem.

b) The Room - after I checked in, me and my wife walked into the room and saw 2 single beds. We were quite shocked as during the check-in, my wife was with me. The bell-hop walks in with the luggage, takes one look at us and looks at the bed and starts calling reception. At this point I figured the bell-hops are way smarter than the check-in staff. We eventually moved to a room with a king size bed.

c) Concierge - I needed to go to a particular address so I asked the concierge . He called them up and asked for the location. Eventually he pulls out a map and with a pen, highlights a neighbourhood area roughly 3 blocks in size. So I ask him, where is it? He then circles at the whole huge area. He then just stands there as if he's done his job. I then ask him, how far is it? He then says 5 to 10 mins walking distance. Since I didn't feel like walking I ask him to give directions to a taxi. I take the taxi and I get there. More like 10-15mins by taxi! Glad I didn't take his advice.

d) Furniture and Fittings - I've had way better 5 Star hotels. Don't expect LCD Screens with beautiful contemporary furniture. Expect worn down furniture with very old fittings. This hotel has seen better days and is due for a re-fit.

Overall - the staff are unhelpful and they don't understand English. I've recently been to Japan and felt that although they don't understand English, their service level is way better. This hotel is supposed to be a 5-Star hotel. Doesn't feel like it. Would I pay money for it? Nope. I've been to different hotels around the world and this isn't world class. Its provincial.

Booked a premier room on the Horizon Club floor. It is a roomy mini suite with all the amenities. Free in-room wifi, razor blades, toothpaste and toothbrush, a scale, and even a nail clipper. Complimentary bottle water and fruit baskets are refill each day. The room was very kept and very clean and the bathroom was large and the towels are the thickest and largest that I have ever encountered. The services quality and the staff's attentiveness is world class.

My only disappointment about the hotel is the quality of the food. We tried all three restaurants/café in the hotel and the quality left much to be desired (I was told this is typical in all hotels, in fact the Horizon Chinese restaurant was one of the highest rated hotel-based restaurant in the city. Tried to venture out for some local restaurants (cab fares are extremely cheap in Beijing). The high quality local restaurant will cost less than 1/3 of what is costs in the hotel and much better quality.

Very well run hotel, ideally placed for business and financial centres, close to Embassy district, but a little way out for City centre.....not necessarily a bad thing ( as its quieter) but not many restaurants or bars around other than in hotel, which are very good but expensive by Chinese standards. Good spacious rooms, very efficient service

I stayed there twice last week - the beginning and end of a business trip to China. I stayed in two other hotels during the trip, and this was clearly the best. The rooms were clean, in good shape, and the housekeeping staff did a great job. They had all of the five star amenities, except for maybe a bathroom scale. They had a buffet in the restaurant for breakfast each day, and for dinner the one night I went to dinner. Great selection. Its a pricey hotel to be sure, but at least you get solid service.
Some people said this is off the beaten path, but for business I think it was fine. It was a ten minute walk to the Silk Street Pearl Market (a great destination to score bargains on almost anything - sort of like a flea market on steroids in a shopping mall format) and a new higher end mall called "The Place"). There is a lot of construction going on in the neighborhood.
The conceirge staff was capable. Everyone spoke English, I used the business center and the people there were helpful too. I visited the mall that is built-in to hotel. It is mostly high-end very expensive stores. There is a Citi-bank with an ATM (you have to go outside to the street to get to the ATM), and there is a grocery store.
