Location in town center, steps from shopping street, old town, river banks and the U Bahn station. Clean and nice room and bathroom. Not a problem sharing. And best of all, Alexander's wellcome and care in everything, including a superb breakfast.
We stayed 6 nights at Alex's B&B during the Messe Frankfurt. His place is very close to the train to the Messe, shops and restaurants. It was clean and well lit. Alex made us a lovely breakfast each morning with yummy coffee. The bathroom is shared. It has a great shower and there is a washer/ dryer if needed as well. I would highly recommend a stay at this B&B. Alex helped us book tickets to Berlin on the train and was always willing to share his information about the city.
