I stayed 2 nights and it was great experience.
Though it’s just 100 m away from crowded & not so nice street, it’s calm, tidy & comfortable. Rewe to-go, a nice convenience store is just 30 meters away and Tegut, a big supermarket is close. There are many restaurants near and it’s close to city center.
The room is good, clean & comfortable. If you look for a luxury hotel near city center & central station, Amerin is the right place.
