I was in Bastien's place for 4 days with two friends and we had an amazing time. The place is very well located, 200 m from the subway, with supermarket, bakery and lots of restaurants nearby. The apartment has everything we needed for our stay.
I haven't met Bastien but his friend Olivier was really nice and gave us the information we needed to start our lovely days in Paris. I would definitely recommend it and return if I have the opportunity.
