Melissa's place is a nice, cozy apartment, great to use as your base while you walk around Paris
Undoubtedly the best thing about the place is the location, first because its close to a lot of the more interesting places (the louvre is just a small walk away, notre dame practically around the corner), secondly because there's quite a few metro lines nearby, and lastly, because its in the middle of the latin quartier, the best place to be if you are a tourist coming home late: the area is well lit and filled with people at all times so you feel quite safe at night, and you'll find a lot of places open to buy dinner or takeaway (even a small supermarket that I dont think I ever saw closed), which doesn't happen in other parts of the city
