Stayed here for 5 days. Two for tourism, three for the Rock en Seine festival as well as tourism in the morning. If you're going to said festival, this hotel is a 15 minute walk away from the festival site, and after a long evening of concerts there's nothing like being in bed quickly.
The hotel was just okay. My room was small and so its bathroom, but the bed was confortable, shower and TV worked as expected, was also clean, and the staff was friendly. It's far from the city center, but the metro is almost at the hotel's door, and will get you to most of Paris' attractions without a line change, but you will start from almost the start of the line, so it will take a while. Next to the hotel there are some bars as well as a supermarket.
Now, for the cons... the breakfast is insanely priced at 13€ per day. I can't speak about how it is since I just eat something on the way. The wireless, while it was free, was at times slow, and its login system was just broken or maybe I didn't figure it out, but you can just bypass it: every time the system tells you your time has run out, just create a new account (you can use whatever as name and email, it won't send you a verification and it doesn't even check if it's a real email). It also was a little noisy, not much, but I'm still used to sleep with earplugs.
Parking in premises was more reasonable at 12€ per day.
So overall, if you're going for tourism and don't mind the subway ride, it's worth checking. Note that I'm basing that review on the fact that I booked online at 60€ per night. In the hotel itself, rooms are advertised at a price of 160€ per night, and if I had paid that, I would have expect better. less
