One of the perks of booking a first class train ticket is the opportunity to use this lounge run by the train company DB. It's a quiet space where you can sit down in comfort with very clean bathrooms.
A coffee machine with high quality coffee and a soft drink dispenser too.
It was worth paying the 30€ extra (15€ each) to upgrade our
Düsseldorf-Munich train journey to first class to be able to use this
lounge, the clean washroom, a hot cup of coffee and the advantage of
seat selection before the journey.
