Directly across from the University of Colorado Boulder campus, this updated residence in University Hill offers exceptional convenience and investment potential. Perfectly suited for students, professionals or investors, this condo is set within a secure building and showcases thoughtful upgrades throughout. An open-concept layout enhances both flow and functionality, achieved by removing the wall between the kitchen and living area to create a bright, connected space with southern mountain views. The kitchen features updated cabinetry, countertops, lighting and a peninsula with seating, while the living area extends to a covered balcony through sliding glass doors. Exposed brick accent walls in the bedrooms add character and warmth, and the primary suite provides direct balcony access. Additional upgrades include refreshed bathrooms with modern finishes and three new mini-split A/C units for year-round comfort. Residents also enjoy access to a rooftop deck with sweeping views. With the option to purchase this unit fully furnished, this condo offers excellent residential and investment potential.
