We loved this apartment which is in the northern Marais area, close to several Metro stations, about 15 mins walk from the Pompidou centre and about half an hour to get to Notre Dame/Latin Quarter etc on foot. It's on a cool street with some nice restaurants and a fantastic boulangerie close by but is also nice and quiet. The apartment is great (fantastic shower and VERY nice lighting Alexandre!) and has all the essentials, we took our two girls age 10 and 13 and for us, it was a little on the small side but I think if you're just there for a couple of nights that doesn't matter at all. Spotlessly clean.
