Room was basic and comfortable. There was an initial problem with check-in because they couldn't not find our booking (4 rooms).. Not the most glamorous of locations but if it's just somewhere you are looking to get your head down and plan to spend most of the day out in Paris then this is fine, if you want more than that, then I wouldn't stay here. It was fine for us as we were there for the Champions League Final so it was ok. I wouldn't stay there with my family though.
One thing I would say, the bins in and outside of the car park need to be emptied on a regular basis, there is a massive rat infestation and you can see them all over the place running around in the bins not something you want to see and could be easily fixed by emptying the bins.. Just to note, the problem is outside, no issues inside the hotel.
There is no AC in the rooms, just a fan so expect to feel warm.
