Welcome to 4279 San Ramon Dr! Located in the the highly sought after community of Sierra Del Oro in Corona; this 5-Bedroom 3-Bathroom home sits on a picturesque 10,800 Sqft lot situated on a Cul-De-Sac just below the prestigious Corona Hills. As you walk in, you'll immediately notice the open floor plan concept allowing for natural light to flow endlessly throughout the high-ceilinged living room. The updated flooring found in the main parts of the residence seamlessly compliments the contemporary appeal this unique home has to offer. As you step into the kitchen, aside from the sizable granite kitchen island, you'll realize the custom-built cabinets alongside the granite countertops. Additionally, the various windows in the kitchen allow light and tranquil views into the backyard. A convenient downstairs Bedroom is located next to a full Bathroom with a walk-in shower, perfect for overnight guests or multigenerational living. Upstairs, the Primary Ensuite Bedroom is a true gem, showcasing high ceilings, massive restroom, a large walk-in closet and hillside views. Three more spacious bedrooms are found down the hall adding a more private feel to the ensuite master. Outside, a sizable backyard displays the most stunning hillside views including a patio centered in-between the home and hills. It's truly a prized view that illustrates the utmost privacy.  A "turn-key garage" would best describe the three-car garage: embracing epoxy flooring and built-in tool cabinets.
