We had a nice stay here.
Pros
-Very very friendly staff (at check-in, staff gave a thorough rundown of where we should go)
-Cool decor (lots of reds and purples, stylish wallpaper)
-Comfortable and room was comparatively large for Europe
-Very affordable price
-Near sightseeing such as Moulin Rouge, Sacre Coeur
-Close to train station and bus stops (for the more in-shape, quite possible to walk to Seine)
-Free bottled water! Free WiFi!
-Free gift if you refuse cleaning services
Cons
-Not a bunch of untouristy food places nearby
-Could get a bit loud outside at night (probably because of bars down the street)
-A little dirty (found bug first night)
-In a somewhat seedy area (lots of sex shops on the way to Pigalle; we didn't care, but if you're going with your grandma, might want to do some research)
Overall, we had a great stay and would consider staying here again.
