I've used Airbnb for awhile now, and it's always a pleasure finding those places and people where the host makes your stay excellent. It's always the mark of a good stay when I can look back on the travel and think of my stay at a certain location as a highlight rather than an afterthought. Erhard was a great conversationalist, and also saved me some grief in visiting Zugspitze (it was raining). He is certainly a person I would look to staying with in the future. He strikes me as a particular man, and very detail oriented-which is reflected in the quality of your stay.
