It's not about getting a place to stay, but sharing with people. So far, I have only hosted one person and it was a nice experience. In the following months I will start traveling more and would love to meet some locals (and travelers too) and occasionally find some places to stay.

Almost everything that can be ranged between Pink floyd and Zitarrosa. I guess you don't know Zitarrosa - I could say it's Milonga but you probably don't know it either. :)
