Very cozy hostel set in a tradtional chinese hutong. Close to subway station which means you have access to everywhere in the city. Western toilets are a huge plus (if you hate the 'squatter' style) and are always clean. The plumbing is in order and hot water is plentiful. Rooms come with heaters and air conditioners which are needed in winter and summer respectively.
Staff here is the best that you can get. Everyone is friendly, outgoing, helpful.
