We loved our stay at Benoit's! The appartment is VERY conveniently located, within walking distance (10-15-20 minutes) to all the major Paris attractions. It's also very close to the subway (Odeon, St. Michel) and RER that can take you to CDG in less than 30 minutes.
Right in the closest neighbourhood there are dozens of restaurants and cafes, pubs & small stores. It is very lively all day and half of a night long.
The place easily fit 4 of us (there are 2 separate bedrooms, each with own bathroom) + fully equipped kitchen and living room. You can cook there with all the cookers, ovens and pans.

Both beds are comfy and rooms are spacious and fully furnished. Nothing was missing. We only wish we could stay longer.
Benoit was responding to all my messages in few hours max. and prepared us really good starting pack for our stay in Paris. He was also flexible when arrangind our check-in and check-out.

If I'm every going to stay in Paris I would not hesitate to book the same place again.

Two small watchouts: there's no elevator (though it was not a problem for us to climb stylish stairs and just 2 floors) and it is quite noisy outside, due to all the restaurants downstairs. It didn't bother us that much as only the living room faces the street and nobody slept there.
