There is almost no common space. The restaurant is closed till6 pm, and no other place to go apart from your room. Also, we were left out one night in the weekend, and without a working phone we could have spent the night in the car..
The hotel is very clean, very well organized, has a nice restaurant popular with the locals, the management is quite accomodating (unlike many other properties in germany). The breakfast is very good, wonderful tea, honey, salmon, meat cut, brown bread, pastries, scramble eggs and half boiled, cheese, although some stuff are not too fresh (some cakes and fruit). The place is far from city centre but a tram runs from there itself to the main square, if u have a car or you dont mind the travel time is good. The staff is really nice and helpful, although at times finds it hard to go beyond the expected. This is very common in Northern Europe as compared to other countries, so be prepared for it if used to travel in Asia/southern Europe/middle East.
