The whole family was very nice and helpful. They tried their best to communicate in English. Even though they live next door, they didn't interfere at any time. Their modesty reflects in presenting the flat location: it was better than described! You feel like spending the time at the feet of the Eiffel tower in a beautiful Haussmannian street.
Perhaps the only minus is the fact that there are only two small roof windows so that the room was a bit stuffy, but pictures of the apartment really do show its actual looks.
We sincerely recommend this host and her apartment, especially for a couple.
