I spent 8 night at Carole's place. The location is great and I felt right at home! It's within walking distance of a mall, plenty of restaurants, grocery stores and best of all the closest metro station is only a few feet away from Carole's building. I've stayed in this area before and I particularly like it because it's away from all the hustle and bustle of the more touristy areas and provides a more authentic Parisian vibe. And the tourist areas are all only a few metro stops away, should you choose to explore them.
The flat itself had all of my preferred amenities including an elevator, secured entry, a washer/dryer and a full kitchen (rather than one of the mini versions that you sometimes find in the smaller flats). This place would be perfect for a couple or small family.
Overall, Carole was an excellent host. She met me at check-in and provided a thorough walk through of the flat. She had plenty of reference materials and recommendations for visitors and was kind enough to inform me of upcoming events that could potentially impact my travel plans.
The only cons that I can think of is that such is the case with most Parisian flats in the winter, the flat was prone to getting a little drafty; however, the radiator units did a good job of keeping the place warm. Also, for anyone that's sensitive to noise, there was some significant noise from the upstairs neighbors in the early morning hours. I suspect they didn't have carpeting on their floors which is why so much sound transferred through. This is something to keep in mind for those who may like to sleep in.
