Our hosts immediately made us very welcome by their very relaxed but enthusiastic manner. We were offered coffee and invited into their "family". Jean-Philippe and Xuong suggested lots of activities for our stay, accompanied by an audio tape, maps and TV documentary which we found most helpful. Background on Switzerland was also interesting.
J-P also offered to give advice for any major purchases, and costs of services.
They allowed us our own space while staying with them. The accommodation was extremely clean.
