I booked Heinz's place on behalf of the Make-A-Wish Foundation for one of our wish families. They had an amazing time and could not say enough about how great this place was! It was the perfect location, a gorgeous space, and Heinz was an excellent host. They also talked about how friendly everyone in the building was to them. The owner of the cafe (conveniently located just downstairs) treated them like long lost friends and helped make the experience even more special. I would absolutely recommend booking with Heinz (specifically this awesome apartment) when you visit Berlin!
