I stayed on Andreas' apartment with my girlfriend for 4 days. The house is big, well equiped and convenient and has everything someone will need for his stay. The location is very good, not in the city center, but there is a tram station just outside the house and the tram takes you to the center in less than 20 minutes. Andreas is a very friendly person, willing to offer his help in whatever you need. I would recommend his place for stay without hesitation!
