This place has a great location in the city and has everything you need! The subway station is close (just a few buildings away) and you can also walk to Galeries Lafayette or the Opera and so on. The room is very clean, modern, and nice, with many useful supplies (dishes, hair dryer, scissors, etc.). You can even cook and watch TV. Coco was friendly. I am pleased and would stay there again.
For others, please note that the staircase is very small. I do not recommend bringing any large luggage. I had carry-on-sized luggage and it was alright, but it would be difficult to get a big suitcase up the stairs. Also, the shower may be a bit small for very large people.
That aside, it's a perfect place to stay :)
