Johannes is a great host. She was perfectly available to answer our questions whenever necessary.
The house was confortable; however, there were 3 issues that might need some improvement: the wi-fi, the absence of a couch and the existence of only 3 adults chairs. There is an extra chair, but it's for a child, which is not quite confortable for an adult.
Despite that, the house is good and a good place to accomodate a family with children :)
