Matchday dates
Listed below are the group-stage matchdays by date, plus accommodation booking links and suggestions for each game.

Alternative options:
In case the host city rates are already too high for you, I've also listed an out of town option that you could try. In each case there is a direct rail link. The times I've shown are from main station to main station using local or regional services, not express trains that are excluded by some rail passes like the Deutschlandticket. If you have an Interrail pass, however, you can use express trains, so could reach the out-of-town locations faster.

All kick-off times shown are local time (CET).
