Klaus's house is a very beautiful house in a very quiet neighborhood; and I would recommend the place if you do not mind being away from main tourist area and prefer quieter area. The house has a beautiful park next to it if you feel like going for a quick run or a walk.
The property is maintained by third party (as Klaus was away) and perhaps due to that they were not able to offer any flexibility of early check-in or late checkout which was unlike all the past AirBnb experience we have had so far.
