We stayed at Laurence's place for two weeks. It was a family trip and we were 7 people (including one child).
First of all I have to say that Laurence was always very fast responding my messages and her communications skills are very good.
Location wise, the apartment is very convenient. We could walk to Eiffel tower and to the Arc of Triumph. Taking the metro was very easy and there are a few metro station/bus stop options close by. We felt very safe walking up and down close to the apartment. There are a couple options for groceries and a lot of restaurants and stores.
The apartment was very clean and had all the supplies needed during our stay. Comfortable beds and table big enough for all of us. Although the tiny kitchen we were able to arrange ourselves in a way we didn't have trouble using it.
Laurence was always prompt to help with anything we needed. I definitely recommend her place to anyone who needs a quite and comfortable place to rest after a long walk day on Paris.
