OK, let's start from the beginning... The hotel is not properly cheap, but you would expect that from a Hilton, meaning that you'd expect a little bit more for your money.
There's no parking available, and the closest around costs 20 a day given the location. When we arrived at the room, there was 2 hand towels in the floor dirty and the water bottle at the minibar unsealed. Even after we mentioned that at the reception on our way out to a walk, it remained the same until next day's cleaning (the bottle was never exchanged). BTW, the room cleaning only happened around 16h the next day, when we were already returning from our city trip. The automatic system made a deduction on our room bill since we took the bottle our of it's stand, so be aware of what you touch and check your bill at the end :)
Additionally, everything is paid. You want to have internet at the room, pay 10 a day (or 15, if you want "premium" internet). Fancy an on-demand movie from the entertainment system, add another 15 a movie. I would understand this if the rates were lower and it compensated in additional services, but with the prices on the top tier for a 4 star, I'd expect less greediness from the chain.

Now the good stuff, because there were some, the Brasserie is very good and the breakfast there was very nice. The staff at the Brasserie and reception was always very nice, and they didn't even tried anything when we complained about the water bottle at our bill for instance.
The room quality/conditions are good, but nothing luxurious, which was very fine for me but nothing that would make you wow in case you expect to match for being a Hilton.
The location of the hotel is very good as well, very close to the cathedral and at a walk distance of most attractions.
