Convenient location, Awesome shower, Responsive host.
You can catch a taxi just outside of the front door or walk down the block to take the metro anywhere in Paris you'd like to go. Local restaurants, grocery, wine stores, electronics and department stores are all within walking distance.
It's very close to the Moulin Rouge, for those looking for that experience, but far enough away that there isn't a heavy concentration of tourists. Access to the food, wine and other sights for which Paris is known are also easy to access with a handy map of the metro.
