Marc's apartment is in a great location in Paris, really close to the Louvre, Marais, the Seine and additionally a large metro hub that allows access to majority of the city. The street is full of cafés, grocery stores, pharmacies, etc. which was helpful and fun for our stay. Marc helped with any and all problems right away. Only downsides are the washing machine seems to be broken and the smaller bathroom has a plumbing problem, but other than that the apartment is great.
