Simon's place is excellent for all your needs and wants in Paris. It's ~15 minutes away from the Gare du Nord and 5 minutes away from the nearest metro station (Chateau Rouge). There is a market with fresh produce next to chateau rouge every day and from there to Montmartre is just a 7 minute climb. Stylish place, super comfortable bed, everything was clean, bathroom was also really nice and even though I didn't cook during my 6 day stay, all the cooking utensils were there. I recommend this place as super great value for money!
