In Bariloche for 90 days where to stay, part time work, banking

Hi does anyone have experience living in Bariloche? Cost of living for stay of several months (not sure I can rent an apartment, pretty sure I can't afford a hotel for 3 months)? Bank account for foreigner who does not have DNI? Western Union or other option to get USD in to Argentina in case I have an issue with ATM/credit cards? I will not need to work in Bariloche although do need to get some cash either from overseas or possibly teach English or do something like that work part time to get spending money. Thanks!
