Where to store luggage before Kedarkantha trek?

Hey,

I am planning to go for a Kedarkantha trek this December and I will also be carrying my extra suitcase and a laptop with me for personal reasons. I cannot carry this extra bag and laptop to the trek. Can someone please let me know where can I store my personal belongings for 4-5 days?

I am doing this trek with the Himalayan Hikers.
