I stayed at Hotel Wittorf for 1 night, and most things were great. The location is very close to the outlet and the staff is very kind. It's very easy to feel welcome, even in these Corona times.
The rooms are clean, nice and renovated, but also without option for bathtub. The noise level of doors slamming from other gusts and housecleaning that starts early in the morning is the only things I would mention to be slide negative. Besides that, my stay was good and I would be happy to book a stay there for another time.
