Very good location near to cafés, restaurants and buses (I recommend Die grüne Kaffeebohne). Comfortable, homely reception area and friendly, helpful staff.
Private rooms are a bit cramped, and you need to be careful with your curtains as there are no blinds and people can and do walk right past!
One last, niche note: if you have static electricity sensitivity like I do, it’s probably best to look elsewhere. When wanting to relax at the end of a day adventuring, repeatedly getting zapped just by moving around the room is not the best feeling.
