Pet friendly hotel with a patch of grass where the parking garage is located. About a 10 minute walk to the old town (Altstadt). Great location, clean and quiet hotel. One complaint - the heat. It's freaking HOT! The room we had only had windows that opened to the inside of the hotel (it was two buildings and they joined it by making the reception are the "middle" so some windows only open towards the reception (middle) of the hotel. It was so hot, we did not sleep as well. We turned the thermostat to the coldest, but nothing happened.
