This hostel is a really, really beautiful and incredibly stylish hostel in Lindau. If you travel to Lake Constance you should definitely stay at here. One of the best boutique hostels that I know. Absolute recommendation.

There should be no "if" about a trip to Lake Constance and Lindau - it should be a must!
