I stayed for three nights in a king room.
Location was what I liked the most about this hotel. It is a short walk to Tuanjiehu subway station, and a short walk away from the Sanlitun area. A cab ride to the airport in the morning takes about 45 minutes. Traffic will be brutal in this area but if you plan on taking the subway or taxi, it shouldn't be a problem.
The hotel has a youthful vibe to it, similar to Ovolo/W/Aloft hotels. The quality of the room and service was very good. It used to be a state owned hotel but has been renovated recently so everything was quite new.
My room didn't have a minifridge, but I didn't need it. The only thing I felt was missing was sticks/spoons for stirring for the nespresso/tea station, since I like to add sugar to my coffee.
Overall, I enjoyed my stay very much and I hope to stay here for my next trip to Beijing.
