If this place is available on the dates you're planning to visit Montreal, do not hesitate to book it. Louis and Gordon have created such a wonderful little apartment/home and they've gone above and beyond the standards of any luxury hotel in which I've ever stayed.
It's almost as if they've made a game of trying to anticipate anything a guest might need and ensured they have it covered. Extra towels? Check. Plenty of pillows and blankets? Check. All conceivable toiletries/bathroom essentials? Check. Fully stocked kitchen, including basic breakfast and snacks? Check. Frosted beer mugs? Yup. A huge selection of tea & coffee? And on and on it goes.
Also, they are immediately reachable for any questions. I can't say enough about how nice the experience was!
