We had a very lovely stay at this place! Sonia is an amazing host! We didn't have the chance to meet her in person, but check-in and check-out were fantastic, Sonia answered very quickly to every question we had and she was very thoughtful leaving a ventilator for us and arranging "last minute curtains" at all the windows for the very hot days we had in Berlin. We are very happy ad hat a wonderful experience! Grazie mille again, dear Sonia! And hopefully will meet some day back in Berlin... :-)
