We stayed in Ariane's place for 8 nights in early June '18. It's a stylish and clean place that was perfectly suited to our needs. A little quirky, with the top floor sloped ceilings, but to us that really just added to its character. The fact you could open up the small balconies and go outside, to look over the rooftops of the Marais was amazing, a a peak around the corner of the roof you can see the top half of the Eiffel Tower.
Ariane was very organised, and our check in procedure was simple and provided us with all the info we needed to get the most out of our stay. She also provided some great tips on local dining and bars, which we made good use of.
For anyone looking for an authentic Parisian experience, then look no further than this place. It's walking distance to all the major sites and is surrounded by fantastic restaurants and bistros.
