I am a industrial engineer graduated from Universidad Catolica de Chile, and live in the residential area at Providencia(one of the nicest zones of Santiago). I lived in Germany and Belgium for couple of times and have the chance to share with other cultures, and learn (website hidden) Santiago I work at my own company at renewable energies.
At home I usually like to invite friends for pasta or BBQ. Or simple share a glass of good wine or a cold beer.
I have been sharing my appartment with roomates from Italy, Germany, France and USA. I think the most important of sharing appartment as the local, is to be friendly and help your roomates feel at their own place and at the same time take attention of cultural issues and be respectful of that.
