Great location! We are two adults and two teens. The space worked well for our family. Central and easy to get to other areas in Paris. Two main metros (Reaumur/Sebastopol and close to Chatelet Les Halles). We arrived RER B from CDG to Halles and walked about 9 mins to the apt.
Restaurants close by (French, Thai, Vietnamese, Japanese, Middle East and even burgers etc). Bakeries are excellent! We went to Midore (corner of Rue saint Denis/Rue Reaumur) for macaroons, petit dejeuner, gourmet sandwiches and coffee Grocery stores close by but best to go to Monoprix for all groceries, wine, bread and pastries.
We enjoyed our time in Paris!
