It was a very nice stay. - The staff is very friendly.
Pros: The breakfast was very very good for us, everyone liked it and everyone was full :) The rooms were very spacious and well-maintained. It was quite noisy because we had to tilt the windows due to the heat in the room, - Here an AIR CONDITIONING would be really VERY HELPFUL. - Therefore, the 2nd smiley from the left at the question: 'How quiet was it in the room'. - But such systems are relatively quickly installed ;) Cons: No air conditioning in the room, which allowed noise from the backyard and the Dortmund nightlife including heat into the room.
