Barbara is a great host! She has a very beautiful and clean apartment which is always scented. For me it was a great experience. Despite not speaking a word of German and Portuguese, I was able to communicate with her since we both made good use of Google translate.
She was even kind enough to share freshly baked brownies and also help me store my heavy luggage during my stay.
Other than that Barbara has amazing flat mates who are also very welcoming.
