A private, south-facing balcony frames serene views toward the escarpment, offering quiet, peaceful surroundings and facing away from Fourth Avenue. Two generous-sized bedrooms, including a luxurious primary retreat with a walk in closet (1.5 x 1.7 m) and a spa inspired ensuite bath. Additional conveniences include an in suite laundry room with stacked front loading machines and an owned hot water heater. Included: two parking spaces, one exclusive underground space and one exterior space, along with abundant visitor parking for your guests. Residents enjoy premium amenities, including a well appointed fitness centre on level 2 and an impressive rooftop terrace complete with BBQ facilities and a stylish party room. The location is exceptional: just 600 metres from Niagara Health's Marotta Family Hospital, home to the renowned Walker Family Cancer Centre. With quick access to both the 406 and QEW, and surrounded by upscale retail, dining, grocery, and banking options, this address offers convenience without compromise.
