Capture front row views of Aspen from sunrise to sunset, in this elegant four-bedroom single family home within walking distance to the core. A light and open floor plan places the main living room, dining area, and kitchen on the upper level, complemented by a family room adjacent to the kitchen. Two fireplaces and walls of windows frame dramatic mountain scenery, creating an immersive, close up perspective of Ajax. The covered outdoor terrace is an ideal setting for entertaining, complete with a BBQ grill and dining table, and offers an exceptional vantage point for watching fireworks illuminate the slopes of Ajax. The main floor features a primary suite with a spa-like bathroom and soaking tub. The lower level offers high ceilings, three bedroom suites, and a comfortable media room with a wet bar. Additional features include a mudroom, laundry with two sets of washers and dryers, and a two car garage. Smuggler, Rio Grande and Hunter Creek trails are close by for hiking and biking, while downtown Aspen is only a five minute stroll away.
