Helene was very responsive to all issues. The A/C had broken down on the day of our arrival and she was so prompt with getting that fixed right away. This was essential as we arrived on the week of the massive heatwave which hit Paris! I am also told that A/C is rare in Paris flats! I did have to message her for some issues and she always responded quickly and efficiently!
The flat itself was very clean, the bathroom was large and bright, and she thoughtfully left us chilled lemon water in the fridge. Location of the flat is terrific too - close to metro stations of lines M8 and M1 - and there are many good eating places nearby as well as supermarkets. We had a wonderful stay here! Will stay again when I return to Paris.
Do note that it is a loft apartment so the upper two bedrooms have roofs which slope down quite steep and as with many flats in Europe, expect to carry your own luggage up two floors.
