Definitely the best location in Berlin. Not only for the commercial Kudamm str. but also for the neighborhood, transportation and the facilities around. We stayed Charlotte's place for 1 month with my partner and we had a great time. Many things were available in the apartment, from garbage bags to detergents. Charlotte's lovely brother Francesco helped us during check-in and check-out. It was a pleasure to spend our last month at this place. I definitely recommend.
