We arrived with two cars in the afternoon. Even we did correspond with the hotel, nobody told us that it was a "City Feast" where the entire centre was closed until 21:00. Nobody advised where we could park int he vicinity and we ended having to carry our kids and luggage across the center city which was packed with people.
We got 3rd floor rooms, which was good for the noise, but bad for carrying luggage up the stairs since there is no elevator.
The hotel did not mention that it is not possible to park and unload/load anywhere near the hotel. We left on a Sunday, so we got away with occupying a spot marked for disabled and a bus-stop.
We did not meet one single employee during the stay.
Strasbourg is great, but be aware of the hotels that tell only parts of their story.
