Description

Iconic and adorable, this 1920s jewel box in the heart of Mapleton Hill was recently restored and updated. Perhaps the most recognized house in Boulder, its unique casita-style architecture is eye catching and coveted. Over the years, the owner has received numerous unsolicited offers to purchase this property and now it's finally your chance. Restored by an artist with a passion for design integrity and the finest materials. Beautiful hardwood floors, original doors and hardware, new kitchen with a SMEG fridge and a Bertazzoni range, and a new bathroom with a vintage claw foot tub and Strom plumbing. Sweet corner lot with fenced yard, stone patio and sprinkler system. Awesome location, walking distance to downtown or Ideal, and close to Sanitas and trails. Last rented for $4750 a month.
This property is off market, which means it's not currently listed for sale or rent on Trulia. This may be different from what's available on other websites or public sources.

    "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!"
