Travelling to Qianmen East bus stop from PEK?

Hello Sir, I'm staying at Muji Hotel Beijing at the end of October. Pls confirm if Beijing West Railway Station Line is the correct shuttle bus to take and if I should alight at Qianmen East bus stop? May I know how far the walk from Qianmen East bus stop to Muji Hotel at Xicheng district? Is Qianmen East bus stop exactly located at Qianmen subway station since this station is permanently closed? Xie xie...
