Description

Location, location, location! Just a few blocks from Pearl Street and perched on a south-facing corner lot directly across from Mt. Sanitas, this five-bedroom, three-bath home is a must-see! Inside, windows have been strategically placed to capture amazing Flatirons views, as well as the sun's warmth and light. On the main, you'll find wood floors throughout and comfortable spaces, including the living and dining rooms, kitchen, study/bedroom, and a full bath. Upstairs, the breathtaking views continue in your primary bedroom retreat. This level also includes a large full bath with soaking tub and another bedroom.

    "West Pearl is truly a neighborhood unto itself, with a variety of shops & cafes and easy access to trails. Start your day with some tea and scones at Spruce Confections, enjoy browsing various antique stores and Two Hand Paperie, then select a bottle of wine at West End Wine Shop. Lolita's is conveniently located across the street to pick up last minute groceries for dinner, or you can enjoy a slice at Nick and Willy's and have some confectionary treats at Piece, Love & Chocolate. Settlers' Park is just down the street, as well as the trail heads to Red Rocks & Sanitas, and the Boulder Bike Path. When you live here, everything that makes Boulder so wonderful is only steps away!"
