Nicolas and Helene are great hosts - very relaxed and trusting, good communications, and helpful with recommendations.
The apartment is very clean and light, private bathroom and use of kitchen.
On the 3rd floor with a lovely staircase (and a lift), it is situated very close to RER, Metro and bus routes, (although we also walked to Paris centre without too much effort too!). Also easy evening walk to Montmartre which is a really interesting area to explore.
