Public Remarks: FANTASTIC LOCATION 1/2 BLOCK TO THE CU CAMPUS! Bright, south-facing unit in a rare, Boulder "higher-rise" building. Located near the heart of CU, this property is walking distance to the Hill, Chautauqua Park, shopping, and miles of hiking trails! Soak in the Flatiron views from the large balcony, or soak up the sun on the rooftop deck (with crazy views!) or at the on-site swimming pool! BRAND NEW paint, carpet and LVP flooring throughout. Clean and ready for your additional upgrades. Quiet, secure building w/ reserved parking, large storage room, and laundry on-site. Great investment opportunity! No pets. Call for a private showing!
*Taxable value of land and structures on it ("additions") is determined regularly by local assessors and does not affect market price.
