Our experience in this apartment was great. Mary was quick to respond and was flexible with our arrival, as navigating the streets of Paris can be intimidating for first time visitors or backpackers carrying their belongings like we were. Mary didn't speak English, but was nice enough to bring her friend and neighbor who did, to translate. The apartment was comfortable, cool at night, very pretty, and directly across the street from a Metro station that can be used to access all of Paris. The only downside that I can think of is that it can be a bit intimidating outside on the street. I wouldn't necessarily call it a dangerous area, but with so many locals hanging out late into the night, standing out as a tourist or flashing expensive items (phones,watches, bags, glasses) is ill advised.
