I stayed at room 004 and paid for that stay around 120€. If they tell you to stay there, just try to find alternatives. I had the windows open for more than 1 hour for the smell to go away, it did, I slept and the next morning it was again smelly. That means that it wasn't the cleaning or the previous tenant etc. The room had serious issue with that smell which I think was humidity. Also, it's the first time I see a double bed room without a desk... The breakfast is one of the smallest I've seen in my life. I would consider as a plus the safety measures, the cleanliness everywhere and also the positive vibes of the people working there. Also, it is nice that it has a yard and you can take a drink there. If the room didn't have these problems I would recommend it with less money ofc. For what the hostel offers and the city of Strasbourg, 120€ is definitely overpriced. You can find cheaper places to stay with much better money - quality balance.
