Where to store luggage for day trip ? West Bus station or Hangzhou Train station or ... ?

Hello,

We will be arriving from Huangshan around 12:00 at the West Bus station and leaving for Shangai in the evening at 20:00 from the Hangzhou Train station ( not EAST ).

We would like to visit the Temple of Soul's Retreat and the West Lake and more if time permits.

1- Is there storage at the West Bus Station ? if yes, should we start our visit from there and go to train station at the end of our visit ?
or
2- Is it better to go the train station ( I assume there would be storage there ) and start and finish our visit from there ?
or
3- other option ?

Thank you
