About this property

An exceptional opportunity to own an executive level residence in one of the region's most distinguished condominium communities. Immaculately maintained and occupied by its original owner (never leased), this top floor corner suite offers a rare combination of privacy, scale, and refinement. Spanning 1,257 square feet, the oversized layout is bathed in natural light and designed for effortless, elevated living. Corner unit = extra window! A gracious, elongated entry hall sets a sophisticated tone upon entry, offering both a large storage closet and a separate coat closet. The open concept kitchen and living area is anchored by stainless steel appliances and an upgraded waterfall edge (quartz) breakfast bar, creating a striking focal point. 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.
