Information for Tenants

The residents in our guest house apartments originate from over 40 different countries and various cultures. We would like to remind you, that in Switzerland, apartment-sharing communities are generally mixed sex, i.e. men and women share an apartment. Should you have a good reason not to share living areas in this way, please inform us accordingly. Provided that enough rooms are available, we will arrange for separate accommodation.
