Looking over the TA list for Beijing this small hotel stands out as number 1. I would say though it is not perfect and has some flaws.
We had two rooms for a family of 4, both rooms with a big (queen size?) bed. The room was a nice size for china standards, with some nice touches.
Free wifi in the rooms, but my room's wifi didn't work, I called down they did something but still no wifi. Used the wifi access from the courtyard in my room instead.
The walls are thin and we could hear others talking in the room next to us, not so good if your neighbours come home late.
The hotel is close to the metro station which makes it easy to get around. A taxi to the Beijing South Train station was about 45rmb. You can walk to the nearby shopping street and market.
Over all a nice small hotel by china standards, would book it again.
