We had a good stay at Katja's home. It is very welll equipped with a large kitchen, a nice living room, 4 bedrooms. The home is quite new, so it is pleasant.
Katja is an excellent host. She is very reactive to answer and provides good advices for sightseeing, restaurants, shops, etc.
Unfortunately, we found the location too far from downtown with no shops around (first one is 15mn walk). The house is located in a new area with only appartments and houses. We were 8 persons so 1 bathroom for 8 is short, especially as the hot water was limited.
