This place is ideally located for anyone who's in Montreal for the food (and really, if you're not into food why are you going?). It opens right onto a busy, bustling street lined on both sides with amazing restaurants, late night bars, and early morning bakeries. It's right in the middle of two metro stations, both within about a 10 minute walk, with a bus (every 30 min or so) right outside the door. The place itself was also spotlessly clean with everything you'd need for your stay -- including a washer and dryer, which was so helpful. The beds are wonderfully comfortable, which was great for a rainy day lie-in. The shower has excellent water pressure. Louis, the host, was very quick to respond before and during our stay. The check in was by keyless entry and thus SO easy, and we definitely felt cared for throughout our stay.
The only thing I would caution is that the place has two flights of stairs (it's one of Montreal's beautifully charming walk-up flats). People with mobility issues, large, heavy luggages or bulky strollers might find the stairs a bit challenging. Otherwise, Louis's place was a great stay for us!
