I am an American who lives in Boston. I studied abroad in Vitznau, Switzerland in 2008 and traveled all over Europe during that time but Switzerland quickly became my favorite country. I now work for EF Education in Cambridge, Massachusetts, and their world headquarters are in Luzern. I will be in Italy for work the following week, and want to stop in Luzern for the two nights before it to revisit my study abroad experience. I don't speak German other than basic pleasantries, but am looking for a safe place to stay for a few nights while I see some work friends from the Luzern office and maybe head over to the other side of the lake near Weggis and Vitznau (hopefully some night sledding on Rigi as well). The reviews for your place sound great and the pictures looks just as phenomenal.
As far as living, I'm a relatively quiet, good-natured guy who has never used Airbnb before but would be a very respectful guest of your home.
