Clemence did make me feel welcome, she set a convenient time for the cleaner to meet us, according to our plans of arrival to Paris, and tried to solve the problem of the hot attic.
The week we arrived was very hot (around 100 F, 40 C), and when we arrived to the apartment, we saw that we can't sleep upstairs, not our kids since it was horribly hot. We spent about 3 hours trying to find a small air conditioner to buy and eventually gave up because it was expensive and we realized we wouldn't be able to carry it by metro anyway. I called to ask Clemence to cancel the stay and she was nice enough to come to an agreement with me about getting some of the money only, even though she has a strict policy of cancellation.
