I'm a writer, teacher and musician from france and germany who will be staying in Rio for three months.
Balthasar was new to Airbnb, so I asked him for references etc, which he provided promptly. He made all the payments promptly through airbnb. There was a misunderstanding about cleaning, which was resolved, and in general he communicated with us quickly when required. I think he appreciated the location and special character of the apartment and the area, and showed a lot patience in the first few days when we were still completing the fit out of the kitchen, and getting in some of the furniture.
This was our first experience of hosting on airbnb, so we all learned a lot from the experience ! The house rules were not fully developed when the reservation started, so our feedback on this point takes this into account.
