There is enought place in the room, big TV, free internet connection with normal speed.
Hotel is in an excellent location, 5mins from the main rail station and the bus stop for the airport direct bus (takes 20mins to get to Dortmund airport for around 8euros).
Also free wifi was very good.
Have stayed here twice now and the hotel is in a perfect location for both Dortmund city centre and of course, visiting the Signal Iduna Park.
Very clean, big room, bath tub, a kettle in the room to make tea/coffee, great breakfast buffet.
Came here for a match at Signal Iduna Park - just 10 minutes walk away.
The rooms were modern and everything functioned well, including the free wi-fi and the water pressure in the shower.
I stayed here for an early morning flight out of Dortmund Airport.
