First ahead the TL;DR-version: Our stay there was awesome, Laure is very nice and the room was idael for the two of us.

Now the more detailed version:

The flat lies in a nice district of Paris and in walking distance of the Eifel Tower, a Metro Station and everything one could need (supermarket, pizza place, ...). The room itself was very clean and nicely furnitured. It was a little bit small, but does fit two people well. Brochures of monuments/museums/etc and maps as well as towels and bedding were provided.
Laure is very nice, helpful and accommodating. She made us a delicious breakfast every morning and told us about sights und museums that are worth a visit. She was easy to communincate with.
We felt very welcome at her place and had an awesome stay :)
