Our family stayed at Nicholas's for a three-day visit to Montreal and we absolutely LOVED it! We highly recommend his apartment, both for its location and comfort and would definitely return.
The neighborhood is great, with many restaurants in close walking distance. The apartment is also very close to the Metro, which is an easy way to move around the city. Street parking was available right in front of the apartment. (Nicholas sold us the passes: $7 CAD/day).
The apartment is beautiful and looks exactly like the photos. Nicholas made sure we had fresh fruit and breakfast items in the refrigerator (so nice!). The kitchen is extremely well stocked with all of the equipment you'll need to cook meals (good pots, knives, cutting boards, etc.). Plus they even have a fondue pot and raclette maker! There is a rooftop deck that would be wonderful in the nice weather.
Enjoy your stay!!
