Mario's place is amazing! Spacious and comfortable. Kitchen is very big and equipped with any kind of stuff you may need to prepare your family meals. Beds are really comfortable and there's lot of space to put your luggage and clothes. Neighborhood is very nice with lots of restaurants and small shops.
Even if very cold outside the apartment is warm and cosy.
Communication with Mario was great, very quick responses and easy to get keys and info.
I would highly recommend Mario's place to anyone visiting Montreal.
