I wanted to stay in Montmartre but had heard it was not safe at night so along Canal St Martin was my second choice. This isn't in the best of spots along the canal (a little sketchy) but as a woman traveling alone I still walked around at night and was fine. Close to the metro and lots of groceries. And if you like walking you can walk to all the major sites. The view from this place though is why to stay. It's unreal. Eiffel Tower to the left. Sacre Coeur to the right. It's a million dollar view for a steal. And Guillaume is a great host having met me at the metro station and walked me to the apartment, showing me groceries and pharmacies along the way.
