How much is the cost by taxi from airport to Courtyard Beijing Northeast ? how about if i use bus ?

If you refer to Capital Airport, hope the following could help!
1. It takes you CNY 50-60 by taxi.
2. If you take Shuttle Bus line14 and get off at Wangjing Hospital, it takes you CNY20. It’s 1,000 yards north to your hotel, so you may take a taxi at CNY15. So the total fare would be around CNY35. Or you can go there on foot.
