I stayed at Remy's apartment with my girlfriend for a week. I really enjoyed it; it has a comfortable bed, all appliances you would need, it is well located and clean. Subway and a supermarket are a minutes away, you can see the basilica from the window, the apartment is on Montmartre which has plenty of small beautiful streets to walk around and very nice cafes. Communication with Remy was pleasant and fast though I didn't meet him - his friend introduced us to the apartment and answered all our questions.
We had a great stay in Paris and would definitely recommend Remy's apartment :)
