We had a great experience staying in Martine and Rémy’s apartment. They were beyond helpful and prompt. The apartment was fully equipped with what you need. The location is great! Every time we came back to our temporary home we could see the Eiffel Tower. Short distances to the metro, bus, rer. Supermarket and patisseries around the corner. Very safe.
As we traveled during winter the apartment was not as warm as we are used to, for the first days, but after that it warmed up or we got used to and it was great :). During winter, if you like your feet warm, you can bring a pair of house slippers.
However this did not take anything from the great experience we had staying at Martine and Rémy’s, still felt like a welcoming home every evening when we returned from our explorations of Paris.
