The apartment itself is well located. Pigalle is interesting as a neighborhood, lots of sex shops around, we didn’t mind it. There are two central metro stations close by. The Moulin Rouge is about 100 meters. You can get to most places in around 15-20 minutes. Montmartre is also very near. A couple of blocks away.
It has a lift which absolutely amazing in Paris. Also the view is very beautiful at night, it is not a balcony its a window. Sometimes it can get a bit noisy on the weekends at night but the space is perfect for a couple, would not recommend for groups. We enjoyed our stay.
