Yest there is a Van seevice from in front of the Youth hostel to La Guardia. It costs $21. I used the service from La Guardia and can recommend it.
That would be the bus. It goes directly to broadway and 103( i believe). Google maps it for the exact bus number bc i forgot. You can get the bus right outside the station. Best to buy a week pass if you're going to be using the Metro all week. Remember to get and keep your receipt after swiping your card at the machine by the stop bc transit police do bus checks!!
The shuttle!! $19 from LGA or JFK and drops you to the door of the hostel. Same thing for returning to the airport. Just go towards "Ground Transportation" at the airport and they'll have a list a different shuttle companies. It's a shared van basically...So pretty much like an Uber pool.
the bus the LaGuardia/queens bus or you can taje a reg. nyc cab about $35-40 from lga to nyc hihostel
