I've stayed seven times, for one to two weeks each stay. The comments below apply to apartments #1 and #2, as I'm not familiar with the newer apartments.
The apartments are well-designed and comfortable, very clean on arrival, and easy to keep clean. The photos and videos on the Loft Jacques-Cartier website are accurate, though the videos give a better impression of the room layouts, decor, and furniture. Annoyingly, I sleep better there than at home.
Loft Jacques-Cartier is located on a tree-lined street in a walking neighborhood, one block northeast of beautiful Parc Lafontaine. Within two blocks is a small convenience store, a bank, a self-service laundry, some small restaurants, several bus stops, and a public bike station (BIXI). About four blocks away is Avenue du Mont Royal, loaded with restaurants and shops, and an all-night grocery store.
The proprietors, Mio and Normand, are friendly and helpful, yet never intrusive.
In all seven visits, I've encountered only one problem -- on the first visit -- involving intermittent Wi-Fi connectivity, which may have been the fault of my laptop. Nonetheless, the next day Normand appeared with tools in hand, and quickly provided a wired Ethernet connection!
I'm looking forward to my next visit.
