2100 USD is not enough to stay in hotels or AirBnB. So he stays in hostels which is maximum 20 euro/day in Western Europe. On remaining 1500 euro he will do just fine.

You can live pretty much anywhere in Europe on 2100 usd.
I've been to tens of different hostels in Europe and to be honest I never seen there drunk people. Most of the people come to a hostel just to sleep there.
