Frank's apartment was like staying at my own place. There's a microwave, a toaster oven, more plates than you can possibly need, and even a fridge! Did I mention I had my own bathroom?!? Frank was available to answer questions but also respected my space. The room faced a garden and was shockingly quiet considering the roads nearby.
The apartment feels like it's in the suburbs but the train ride to the center of town is literally 4 minutes, and the ride to the largest station with long distance trains is about 12. The walk to the station is a lovely tree-lined path next to a busy bike lane. If you feel like staying in, there are quite a few interesting and highly rated ethnic restaurants. Want to cook your own meals? Choose from an amazing organic supermarket, or an exclusively Italian mini market (so many cookies!) or even a standard Edeka.
