I was recommended Martine and Karim's studio by a friend of my family who has stayed with them many times, and I can say that I was not disappointed in the slightest.
While moving to Paris from across the ocean, I stayed at the studio for one week upon landing while waiting for my permanent apartment to become available - I had the most amazing time.
The check-in process was smooth, the studio is equipped with everything you could need to feel right at home, the neighborhood is adorable (truly a village within the city, as advertised) with little markets, lovely restaurants, major grocery stores, and metro line 6 all just a few minutes away.
Martine and Karim themselves are the kindest, most welcoming people ever.
Throughout my stay, I also got to see their other two units, which looked equally as lovely.
Truly, I cannot recommend these properties enough - do yourself a favor and book immediately to guarantee yourself a blissful stay in Paris.
