We were a family of 3 and enjoyed our stay in Charles' place. It's well equipped and comfortable, and situated in a quieter neighbourhood right near a Metro station. The kitchen was particularly well stocked, and we were able to cook a number of meals.
A few things to note. The apartment smelled noticeably like stale cigarette smoke when we first checked in. We also found a glasses case under the sheets of a bed (making us wonder how detailed the clean up had been), and the living room couch had some stains, which didn't feel very hygienic when using it as a pull out bed. There is only one mirror in the apartment (above the bathroom sink), and and it was too tall for the shorter person in our group.
That being said, the apartment is clean and comfortable overall, and I'd recommend it for a family or larger group.
