We stayed at Rita’s apartment in Ku’damm , the location is excellent for walking around the city , or 5 minutes walk to the Charlottenburg SBanh ( above ground trains ) these are great to get around . Plenty of small family run restaurants in the neighbourhood and these are reasonably priced . Two supermarkets nearby 3 minutes & 5 minutes walk away . If from out of Germany remember supermarkets & most shops are closed on Sundays .
