I would like recommendations and suggestions for 3 nights stay, maybe near the railroad station; restaurants; and public transportation. Will be there in May.
No specific place to stay I can recommend in Dortmund since I always stay in Düsseldorf when I want to visit Dortmund. In Düsseldorf I stay in a hotel in the train station area, Hotel Bismarck on Bismarckstrasse, ca 2 mins...all very convenient, internet cafe is Graf Adolf Strasse, 3 mins away. Post office is in the opposite direction towards the Altstadt....3-4 mins away from the Hbf. On Graf Adolf Strasse are also hotels.
Going to Dortmund is direct from Düsseldorf Hbf, you can also take the S-Bahn direct from Düsseldorf Hbf to Dortmund Hbf. (S-Bahn 1). if you prefer not riding the train. Both Dortmund and Düsseldorf are served by the U-Bahn to get out to outlying areas, ie far away from the Zentrum. I've used the U-Bahn to get out to Dortmund-Hohensyburg partially before having to catch a bus to Hohensyburg.
Thanks. That's helpful!
Just got back from Dortmund. We stayed at the Radisson Blu near Signal Iduna. Perfect location for game day and the rooms and staff were great, but a not-great location for everything else. I don’t have a specific recommendation but I’d try to find s place near the shopping mall or the Alter Markt. Have fun!
