Very central location and impeccably clean apartment. Large living room with nice furniture, amazing water pressure in the shower, all your basic amenities provided (cups, tableware, coffee and coffee machine, towels, air conditioning, wifi, etc). The entrance is quite narrow and unassuming but the apartment itself is nice and even the sofa bed quite comfortable. We could walk almost anywhere we wanted to go. As mentioned, Rue Saint-Denis is where a good number of prostitutes work but I never felt weird or scared (the street always has plenty of normal people going about their daily business as well) and it makes for a great story to tell your friends!
