Ralf is very nice and very gentle. On the day we arrived, he helped us carry two big and heavy suitcases upstairs and prepared tea and biscuits for us. Ralf and Rahmat keep their house very clean and tidy. The house is very close to the central railway station and the transportation is very convenient. We like their house very much. On the day we left, Ralf helped us carry the suitcase downstairs before going to work. We were very grateful to him!
