This place is 100% as described and 1000% chock full of charm, comfort and convenience. It's in the heart of Le Marais, which is fantastic for seeing the city. But once you close the apartment door, you wouldn't know it - it's SO quiet and cool inside (thanks to the modern touches that have been added to the apartment such as double-pained balcony windows, and central air conditioning (when needed)). Another great plus is that there is a washer and dryer if you need to clean your clothes from long journeys.
I found myself sad to leave the place and wished I could be living in this place myself. Camille has made a great oasis in the heart of Paris. If you're looking for a modern luxury apartment in central Paris, you've found it - go no further. : )
