My son is staying 2 weeks in Berlin at a friend's house to practice German. I look for a responsible native German young man able to entertain him during the day (8:30 am to 6pm from Mo to Fri) by bringing him in the morning to visit the town (museum etc) in the afternoon to practive sports (swimming pool, football or basket in a park) etc by playing with him and speaking German to him. Picking up and bringing back to his host house (SCHWARZKOGELWEG)
