We 4 adults had a great stay at the apartment in Berlin. The apartment was as described: quiet, enough room for all of us to have our own space when needed, and included everything we needed. The kitchen has everything you need if you'd like to cook-in during your stay.
We were a little later arriving than planned, due to a flight delay, but Tina's friend who greeted us kindly waited although she had somewhere else to be.
The area is fantastic with restaurants and cafes on the doorstep, but as the apartment is through a courtyard and at the back of the block, it is a quiet and relaxing haven.
