I visit Paris quite often for short business trips, my stay at Yukie's apartment was the best experience I've ever had.
My Eurostar train was arriving in Paris quite late afternoon and her friend was waiting for me till late to make sure that I check-in the first day without any problem. Moreover, when checked out, due to my late train back to London, I had to stay in for a bit longer and she was so kind to understand my situation.
Lovely apartment for one or two, nice craft beer pub downstairs, and very creative & multi-cultral area nearby to hang out.
I definitely recommend her place if you are thinking to stay in Paris and love to stay there again in the future.
