Review tips
I was allowed an early check-in which was nice. Ingeborg was very nice and welcoming despite us not being able to communicate very well in person (me speaking English and her German)... But Airbnb made that easy with its translation service.
The room was bigger than I anticipated, which was a pleasant surprise. The bed was very comfortable, and the room also had a desk to work on. Lamps nearby provided necessary lighting when it got dark. She also had a piano in the room which I was able to play after she hooked it up to the power cable!
All in all, it was a very nice stay, and providing the cost is not an issue for you, I would definitely recommend this as a place to stay during your visit.
