No complaints here at all. Good service, great breakfast, great staff. The only problem I found was it proximity to a coal fired plant. But there is not really anywhere in Beijing you can go without being close to one it seems. The photo I have was taking on an extremely smoggy day and everyday was not this bad at all. Also the subway station is very close and the best option to take to the Forbidden City and Tienanmen Square.
I would definitely stay here again.
