We had a great stay at Christophe's place - very prompt and kind host. Apartment itself is great (considering average places in Paris), significant space and moreover having a lot of windows and direct sunlight (which is usually hard to find in Paris). Climbing stairs and the lack of lift is something to take note of, especially if you are travelling with heavy luggage, however it is part of the experience (your daily dose of sports). Overall, apartment is great value for money and neighbourhood is one of the fanciest ones in Paris. I would definitely recommend.
