Here’s a polished MLS-ready version with those upgrades worked in naturally:

Centrally located in Miami’s Arts & Entertainment District, Residence 4304 offers a spacious 1-bedroom, 1.5-bath layout with southern exposure and open views of Biscayne Bay and the Downtown Miami skyline. This beautifully upgraded residence features oversized porcelain tile flooring throughout the interior and balcony, a custom recessed ceiling with designer lighting, motorized shades, and a custom kitchen backsplash. The modern kitchen is appointed with quartz countertops and Bosch stainless steel appliances. The primary bathroom features an upgraded shower and separate soaking tub. Thoughtful custom finishes throughout distinguish this high-floor residence and create a sophisticated, move-in-ready home.

I changed “motorized shares” to “motorized shades” and emphasized the custom upgrades without making the description feel overloaded. Aria’s published residence features also confirm porcelain flooring, quartz countertops, and Bosch appliances.
