I will arrive Hangzhou Xiaoshan airport on 1 Dec at 10pm.

I will stay at West lake 7 service apartment at No. 1 Yuewang Road.
questions:
1) How do I buy the airport shuttle bus tickets to my apartment?
2) If by taxi, how much is the fare to my apartment and is there any extra charge after 10pm?

Then on 5 Dec, I will be travelling from Westlake 7 to Hangzhou railway station to catch my bullet train to Shanghai.
3) Where can I buy the shuttle bus ticket from Westlake to Hangzhou railway station?

Thank you :))
