We loved staying in this loft. Aesthetically speaking, it was super-chic down to the last detail. It is situated on a very quiet street, yet only one block away from the bustling Marais in one direction, Bastille in another, Isle St-Louis in yet another. Beautiful apartment, great neighbourhood, wonderful host. I would definitely stay again.
I would point out, however, that in the mezzanine loft (bed, shower, sitting), the ceiling is just a whisper above six feet high. Tall travellers would want to take note. Everyone else: enjoy this beautiful space!
