Me and my sister really loved our experiencie in Frank's house. The apartment is just like in photos, everything was clean and super well equipped. You have bus, metro and a supermarket (aldi) just 1 min walking. Public transport passes very frequently and you reach the center in 20 min. If we go back to berlin we will stay in this house again ☺ We met Frank and he was lovely with us. So thank you for everything!
