Karen’s apartment was located on the third floor. There isn’t an elevator (or we did not find one) so if you have heavy luggage’s it might be a challenge. The travel guides she provided was super helpful to us. It provided a bit of history to the site we saw. She answered messages promptly, even as a working mom. There’s a washing machine in the building located in the basement which we utilized. Karen was so kind to show me how to use it (since I did not know German) even as she had to go to work so early in the morning. The only cons about this place was the floors. They are old wooden floors and squeak quite a bit. As we were trying to be mindful of people sleeping in the next rooms, it was hard to do. Overall, Karen is an outstanding hostess of an apartment located conveniently next to trains and bus stops.
