Property details
Proto Apartments are just the ticket for easy living in Denver. You'll enjoy brand-new studio and 1-bedroom apartments that feature designer kitchens with quartz countertops and stainless appliances, including dishwasher and microwave. And you're on the right track with large windows, air conditioning, and an in-unit washer/dryer. Additional storage is available, and we are pet-friendly, too. Located in the West Colfax neighborhood just 5 blocks from Sloan's Lake, Proto Apartments are convenient to restaurants, coffee shops, local breweries, and bike trails. We've got all your transportation angles covered -- in addition to off-street parking and bike storage, there are 2 on-site car-share vehicles. Proto is also less than a 2-min walk to Perry Street light rail station, a 12-minute train ride to downtown Denver and Auraria Campus.
