One of the best German Institutes in Germany. I have had intensive courses in this Institute and it's one of the best in the country adding to that it's super location which is in the heart of Dortmund downtown.
Perfect hotel in a perfect location. The hotel is very nice and a piece of art renovated the perfect way. The staff are super friendly. We stayed in a small room but we had a jacuzzi inside which made the experience unforgettable.
