We loved our stay at Sabine's apartment! The location was perfect for us, less than a 10 minute walk to both the train and bus stops that can get you anywhere you want and a short walk to several restaurants, grocery stores, and bars.
Sabine was also very easy to communicate with and responded to any questions we had quickly. The apartment was very clean and the bed was super super comfortable. Also, the kitchen is very well stocked with utensils/pots/pans/etc.
The only thing I didn't like which probably isn't an issue for most people is the lack of a dresser/closet for our clothes. We brought a good amount of clothing with us (Floridians in Denmark in winter) and I personally just like to be able to organize it a bit rather than living out of a disorganized suitcase for a week. But I didn't ask and just assumed there would be some storage we could use so that's on me.
100% would recommend Sabine's place, we had a great time!
