Mathieu's place is sparkling clean and has everything that you would need for a stay in Paris - towels, a hairdryer, an umbrella (hopefully not needed) and all of the things that you would need to cook and clean. We absolutely adored this apartment and we could not recommend it enough. Mathieu is always a message away should you need anything and we found him very responsive and friendly.
On a more practical note, the location of the apartment is close to everything without being too close. You can get to all of the major attractions on foot or by public transport, whichever you prefer. There are loads of lovely bakeries, cafés, bistros and restaurants nearby (Try Georgette for dinner one night).
