If this place is available, I strongly suggest immediate bookings. I had a great time staying at Mehdi's place for a week. It is very centrally located in Paris, I walked most of the time to places (restaurants, shops, attractions, groceries stores). Whenever I needed to use the metro, it is only a few minute's walking distances.
The place looks better in real. I had 3 small balconies to myself to look at Paris streets. Mehdi put efforts into making the place look modern with little touches here and there. It is spacious, compared to other places that I have been to Paris. I felt lucky to stay there.
Mehdi went out of his way to make my stay comfortable by providing me tips for restaurants, places to see. He also responded quickly whenever I need additional stuff for the place.
I will look up this place next time I am back in Paris.
