A hidden gem in a great location for the Moulin Rouge (5mins walk); Sacre Coeur (12mins walk) and Monmartre Village (8mins walk). Close to Guard Du Nord too (5mins on the metro or a 20mins walk). Worth noting that there a security iron shutter that you have to close every night and so there are no windows, so if you suffer from claustrophobia this could be a problem. It wasn’t an issue for us at all and we felt it added to the quirkiness of the place.
