We were late getting in due to the road closure between Austria and Germany heading to Garmisch, but the owner was great and left the key for us with instructions at the front. Everything was very clean and comfortable, and we enjoyed our view of the alps from the balcony. It has a decent sized shower stall as far as European shower sizes go.
We had breakfast there our last day (which you must request ahead of time), and the owner put together a great spread for just the two of us, and even made us fresh boiled eggs. The owner is very friendly and speaks good English. Be sure to have some cash Euro on you to pay the city taxes if they were not included in your reservation. The Wifi also was strong - we never had any issues with the Wifi.
