I stayed at Martin’s AirBnB with my 12 and 13-year olds and we loved the classic Berlin architecture with super tall stuccoed ceilings and the loft beds. Martin is an architect and it shows: everything was very thoughtfully and tastefully designed, with multiple light sources for a cozy atmosphere. I also loved being able to play my music through the Bluetooth speakers. The bus stops right in front so I was able to go see a music show in the evening and come back late and still feel completely safe. Don’t miss Graefestrasse for its many cafes and unique boutiques. Berlin retains an authenticity lost in most other Western capitals.
