Great place! Small but functional!
The studio was very clean and as described. However, some people might be disturbed by the day light while sleeping as there are no curtains.
Having the ability to watch the stars from the bed is a real plus.
The studio is well located near a metro station and Gare du Nord is only at 10 min walking distance. Maeva has been a great host, check-in and check-out have been really easy. I would definitely come back.
