Well, we didn't stay exactly in Europe hotel but in Akena.
The difference? 14€ per night.
Both hotels make part of a complex sharing access and resources, with three level of prices - Akena in the bottom, Europa in the middle, Business Apartments on top. Of course, I can't compare the service, but what I saw in the common areas didn't make any difference, so it must be in the rooms.
Akena room was small but functional, the same applying to the bathroom. The staff was gentle, and breakfast, maybe poor to an American or English, was perfect to a continental. The best? Easy and safe parking, absolute calm and cleanliness.
