Overall very satisfied. We booked one night to visit the Strasbourg Christmas market, so it was obviously more expensive than it would usually be, but still decent compared to other hotels around the city.
The hotel itself is nice and clean. The rooms are pleasant and spacious, if somewhat bare on terms of decoration and appeal. The bathroom could also be better isolated from the bedroom; ours had a glass wall and glass sliding door.
The plumbing is a bit noisy and you can hear when there are people in the hallways, but it is not enough, I think, to bother you while you're sleeping.
Breakfast offer a solid choice of drinks, sweet and savory food; enough variety to please every palate.
The hotel also comes with a brand new spa which is free (for now) for every guest (!)
