Marc's place is a spacious, two-level apartment (sousplex) located a great area of Montmartre. It's an older building that has it's quirks, but is by far the largest place in which I've stayed while in Paris. The main living spaces are on the street level of the building and the bedroom is basement level. There was some foot traffic, but it wasn't noisy and I couldn't hear anything from the bedroom. The location was perfect. Restaurants, shops, and markets are located within blocks so I was able to walk to pick up fresh bread and groceries, which made it feel like I was living in Paris. And when I wanted to go sightseeing, the touristy parts of Montmartre were located just up three flights of stairs from the apartment. Additionally, the apartment was within walking distance of two metro lines so it was easy to get anywhere in the city. I did have some difficulty with communication regarding check-in, but Marc and Diana were able to get in touch with us to sort it out. I also appreciated their recommendations for restaurants in the area.
