About this House

Charming brick home on Dewey, built in the early 1900's. Quirky and unique, the kitchen is small and lacks a dishwasher. The bathroom has the original claw-foot tub. A terraced back yard has a clothes line for solar laundry drying, a large garden plot (needing some TLC) and a storage shed for bikes and such. Fun fact: Bedrooms are upstairs, one to the left and one to the right of the stairs in the middle of the house. Bedrooms are long and narrow and a queen size bed works, but a king will be problematic. Tenant is responsible for lawn care, gas and electricity (Xcel) plus treating this old home with the care it deserves for it's age.
Close to North Boulder Park, and Ideal Market.
Available early September
Absolutely no smoking, no pets and no students. Two unrelated persons. Call Heather to discuss the details at All County Boulder Property Management 720-428-2100 or email hgrant@allcountyboulder.com. Apply online at www.allcountyboulder.com

    "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!"
