I wasn't terribly impressed with Hotel Mademoiselle.
First off, the hotel and rooms were clean an well maintained. There was a bathrobe for each of us with a chocolate-covered marshmallow on each (a nice touch). The shower was awesome...lots of good, strong water flow and a nice, open design with lots of room. It is also conveniently located by the Gare Du Nord train station.
The rest wasn't so good:
I speak French functionally, but didn't quite know how to ask about the spa hours and procedure for booking time in it, booking a massage, etc. The front staff couldn't answer these in English, and there wasn't enough printed information in our room's information folder to be able to translate. So, despite wanting to, we were never able to use the spa or book any massages.
Breakfast was horrendous. The quality was right on par with that of an American Holiday Inn Express, which I regard as the worst I've ever had. They had facilities for soft or hard-cooking one's own eggs, which was the safest bet. A few of the breads were good, but most tasted like they were factory-produced.
They also oddly require you to leave your room key with the front desk when you leave, and pick it up again when you return. One also has to "buzz" the front desk after 11:00 p.m. to gain entry, and that's another added hassle.
The final issue was with the courtyard that our room's window opened to look down at. This also serves as the hotel's outdoor dining area / smoking lounge. There's no air conditioning in the rooms, so when one opens the window to get some air circulation, you're assaulted by the concentrated stench of cigarette smoke. Being asthmatic, this made for a pretty miserable stay. read more
