I stayed at Ludovic's apartment for a whole month as part of a business trip and had a very good experience. I was welcomed by Gregory who was very kind and made the check-in a breeze. The place is small, but very functional, is equipped with everything you need when staying for a longer time, except for some essentials that I had to buy. All in all, it's exactly as described. I loved how close the listing is to the line 1 metro and how central it is to some beautiful sights and the two islands. Since it's right in the Marais, it can be quite loud until midnight, which however wasn't a problem for me.
