## Description

### Agent Description
Perfectly located on one of Boulder's most idyllic streets, this exceptional home blends Victorian charm with luxurious modern amenities. The homes' traditional exterior gives way to a welcoming main level that features light-filled spaces, soaring ceilings, a formal dining room perfected for entertaining, and an array of spaces that welcome the outdoors in. The chef's kitchen features a new Sub-Zero fridge, Wolf range, granite topped island, and a walk-in pantry that makes organization easy. Don't miss the cleverly-designed under stair office with secret bookshelf, one of the many special touches that make this home so unique.Upstairs the primary suite features two fireplaces, a generous soaking tub and steam shower in the spa-like bath, soaring ceilings and mountain views. Two more light-filled bedrooms, two full baths and a dedicated laundry room complete the second floor. The lower level includes the large fourth bedroom with an en-suite bath, impressive ceiling height, an office, third living room, and an abundance of useful built-in storage. Step outside to a peaceful retreat of a backyard that includes a waterfall feature, plumbed-in BBQ, multiple outdoor patios, a two story playhouse, and an array of flowers and fruit trees. The separate backyard cottage with vaulted ceilings, a kitchenette, and powder bath creates the ultimate flexibility for a gym, home office, or guest house. The two car garage with epoxy floors and additional storage adds to the comfort and convenience of the home.Walk to trails, downtown restaurants, and all the best that Boulder has to offer. This is Boulder living at its best
