It's been a great experience in Emmanuel's place, it's very cosy and within walking distance to a lot of tourist attractions(Louvre, Notre dame, opera), it's also very easy to reach from CDG, just take RER B directly.
Before and during our stay, Emmanuel has been very helpful and responsive, we loved the little shops, bakery and cafes downstairs.
The only little issue is that the apartment is on the 5th floor, for those with big suitcases it could be hard to lift all the way up, but the rest of the apartment definitely makes up for it.
