Margaux's apartment is perfectly located for Montmartre and the surrounding area. The nearby streets are full of cafes, restaurants and bars and you are only a 5-minute walk from the Sacre Coeur and the Moulin Rouge.
Inside, the apartment is very well finished with good quality beds, bathrooms and small kitchen. There are TVs in every room. Note that only one bedroom has a toilet, the other uses the toilet off the kitchen (but does have an en-suite shower room).
The apartment is very safe with a good door lock and bars on the windows (it is on the ground floor/street level).
The kitchen was missing a few essential items and we have suggested to Margaux that these are added to help visitors to make a coffee or tea.
Finally, the cellar (cave) is an interesting feature! It is not directly connected to the apartment, it is off the shared hallway, but it is certainly could be useful for friends to relax in, especially in very hot weather.
