We had a wonderful family holiday in Karin's place!
The space works great for large families, and is actually a little bigger than on the photos, we found. The large living /dining area was great for hanging out together, and the apartment was modern, warm, and with a nice view to the park.
We discovered the location was excellent, with only a couple of hundred meters to the centre of Garmisch, with bakeries, shops, ice-skating rink, etc. Also, it took only 5-10 minutes to drive to the Hausberg gondola for downhill skiing.
The interaction we had with the hosts was limited but nice, they were always friendly when we met them, and they responded to any requests promptly.
We would definitely stay again :)
