Can anyone recommend a reliable car service from our Berlin hotel to the Berlin airport? There will be four of us traveling with luggage.
Have your hotel arrange a car for you.
I've used Blacklane in the past, but they have become quite expensive as of late!
Where is your hotel? There is also an excellent S-Bahn service to the airport.
I second the suggestion of the S-Bahn. It's cheap, easy and reliable.
I have also used the Free Now app in Berlin (which will either get you a Free Now vehicle, or a taxi/licensed car share driver). We had a very early flight on our most recent trip, and using the S-Bahn would have involved a bus and another change. Free Now worked great.
