The cheapest way is to get to Qarib Kosh (minoodar) sq in Qasvin the Taxi stand of Alamut valley and get a shared taxi and negotiate to take you to Shahrak village.
I also send you the address in Farsi:
الموت شرقی، روستای شهرک؛ اقامتگاه آله آموت- حسین شهرکی
The other option is we can arrange one private car only for you to take you to the valley.
I also send you the location on google maps.
Thanks!
