There was only one bathroom. Since it is located in altstadt (old town) and this is a popular area for bar hopping, hookah ,etc.there was some noise in the middle of the night. The parking area is kind of hard to find. We had to call the hotel so they could direct us to it.
The staff is super friendly. The apartment is super nice and close to shopping, bars, restaurants, the castle, and the train station. The view (if you get an apartment on the fourth floor) is lovely. You can see the castle from the second level balcony. The apartment was spacious and accommodate five people perfectly. There is a kitchen so you can cook. It also comes stocked with some cookware, dishes, cups and utensils.
