Enlarged sliding glass doors lead from the living room to a spacious deck featuring bench seating under a canopy of trees. Below, the refurbished landscaping is served by a new app-controlled Rain Bird system and a garden shed. Retreat to the brand-new, 97SF studio that is perfect for a private office, art room or fitness space. Luxurious accommodations begin on the main level, with two secondary bedrooms and an updated bath. Ascend the wood staircase to discover the beautifully renovated owner's suite, featuring a sprawling bedroom with Flatirons views, a walk-in closet, and an en suite spa bath with a soaking tub, rain shower, double vanity, water closet and designer tile. The secondary suite on this level boasts a walk-in closet and an en suite bath. This home's extensive upgrades include fresh paint, all-new lighting, new fencing, and completely renovated kitchen and baths. Carpeted garage attic space, a 3-foot-deep crawl space, an instant-on water heater and central HVAC add comfort and convenience. This fantastic location is close to parks, world-class hiking, Ideal Market, Downtown and Pearl Street.
