Going to Berlin next week with 13yr old and 16 year old. Bogged down with work and haven't had time to plan. What's the best way to spend 7 days in Berlin with teens? Both interested in most things, both doing German at school and interested in history.
Staying centrally on Friedrichstrasse. How do I sort travel tickets for us all for bus, U bahn, tram etc. Last time I was there was ages ago, so long ago that I think you bought books of tickets and stamped them. Do I need an app? An oyster type thing?
Thanks for help.
