We had a very enjoyable stay at Frederic's place - very conveniently situated in the 15th arrondissement, just a few hundred yards from fun shopping on the Rue de Commerce, many small brasseries, patisseries, fruit and vegetables, etc. An easy walk to the middle of Paris - important right now because of the strikes and uncertain public transportation - and it felt very safe to walk home even on the night when I was alone (middle-aged, small woman). The 15th in the morning is full of women with baby strollers, middle-aged men in high-priced running gear, and women in high heels and office clothes on scooters because of the strikes - a very residential area. The only inconvenience was that the sole way of making coffee was a Nespresso and it would have been nice to have a Bodum or other way of making coffee.
