Frank's place is as described: it's quiet, very comfortable and tastefully kitted out. It is across the road from the Jungfernheide U and S Bahn station, so transport links were excellent. The flat is at the rear of the property and this, along with highly effective double - glazing, made for a tranquil and pleasant place to chill after a day's sightseeing. There was a lovely dining area which was bathed in sunshine at breakfast time, making for a lovely start to the day. Charlottenburg Schlosspark is very close - great for jogging! We had an excellent stay and would highly recommend.
