The apartment is well-located, near metro stations, restaurants , bars and bakeries. It's exactly as described with a sofa bed, which is just as comfortable as a real bed; separated from the rest of the apartment by a thin curtain so maybe you won't have too much privacy but in my case, Jean-Francois was there to welcome me and he stayed the first night and the rest of the time he was out so I had the apartment for my self during all my stay which was great.
Besides, Jean-Francois was a very nice and welcoming host.
I would only improve the cleaning of the place, starting with the kitchen, especially considering that the price includes a charge for a cleaning fee.
Other than that, I really had a very good stay :)
