Catherine was a very accessible host and quickly addressed any questions regarding adjusting the heating unit. We arrived in Paris much earlier than expected and she allowed us to leave our luggage in the apartment while it was being cleaned. The apartment is in a wonderful location, however it was much too small for 5 adults to stay comfortably, and there is only 1 toilette which is not sufficient for that many guests. Since we only stayed 2 nights it would have been tolerable, but the cigarette smoke coming in from the neighboring apartment made it unbearable. I would not recommend this apartment for non-smokers or families with kids.
