Kasia and Alan's apartment was a perfect home base for our visit to Berlin. Nicely appointed, very clean, and conveniently located near the U-bahn, so it was easy to get around. Kasia was an excellent communicator prior to our stay, and upon arrival she provided us with good suggestions on what to see and where to eat. We highly recommend the wine bar that she suggested...what a fun evening! Many thanks for a good stay.
