Marc's apartment is very charming and makes for a very fun Parisian experience. It is a 17th century building accessed by aged, characteristic stairs. Marc, being a musician, has many cool instruments around the common spaces of the apartment that give the space a creative and fascinating vibe.
The rooms is spacious and comfortable. The location cannot be beat: within a decent walking distance of the Louvre and Notre Dame and very close to a metro stop, restaurants, grocery stores, and anything you need. Having the shower and sink in the room was a nice touch for renting a private room. Like most apartments in Paris, be ready for stairs. Even though the area around the room is a lively part of the city, I did not notice too much noise during the night.
Thanks, Marc, for a great place to stay during my week there!
