We've been a weekend in this hotel for touristic reasons. We decided to go to this hotel as it wasn't really that far away from La Cité, nor the center of the town. In general, Ibis Budget is a safety card. You know exactly what you will find, and usually there aren't surprises.
Things that I like:
Beds are comfortable. The bathroom service is sufficient and usually clean. You don't need to bring soap or champoo as the hotel always provide. Services in general are good.
Things I don't like:
In this particular case, the room service didn't clean the room. True that when we were in, the Privacy sign was put in the door knob, but when we left, around 10:30, we took the sign away so that they know we wanted the room to be cleaned. When we came back, it wasn't. We went in the reception to get clean towel, which they provided.
Other thing I don't like is that the price for the breakfast is a bit too expensive in my opinion. 6,60€ to have a croissant, coffee, and an orange juice, is a bit too much for me. But it's also true that we tried to have breakfast in a cafeteria nearby, and it ended up costing us 10€ for two "pan au chocolat" with coffee. Also, having breakfast in the city in Sunday looks like an impossible task. So, all in all, you might need to purchase that 6,60€ breakfast.
Anyway, I'll keep coming to Ibis Budget, as I know it's usually always clean, and it's services are good enough for my needs.
