When I booked this place, I was travelling alone, but then I asked a girlfriend to join me. Location-wise, it's fab; so much to see and do within walkable distances. Tonnes of great restaurants, 15 mins from Galleries Lafayette (and the bus that goes directly to and from CDG); 25 mins from Le Louvre.
The place is small - just like most hotel rooms- but with a fully equipped kitchen (that we never used as it is so much easier to eat out). The shower was always hot, and lovely to have warm towels hanging on the rack!
Our only issue was the Murphy Bed. It's barely a double (we are not a couple!), and the mattress was unforgiving. Also, there is no safe to lock passports or valuables in ( and the entrance door is glass)
Having said that, the place is secured with entry codes from the street ( one each for day and night), and it is SUPER quiet! Not a sound to be heard from the street.
If you are a single traveller, this is an ideal spot to rest your head after a day of exploring!
