We booked a local Hotel werre we stayed already in the past near Magdeburg.
It was different. No breakfast, no bar, no Restaurant open. But they made a nice breakfast lunch package for every guest. Free of charge. Two rolls, drinks, a nice chocolate. That was really ok.
Being outside the own house for really a long time was a wonderful feeling.
Wearing the mask is not a big deal. You sweat a bit, but it is ok.
