If you're planning to rent your airbnb basement apartment be sure to check the requirements with your landlord. In most cases, you'll need the permission of your landlord to rent your apartment. A Denver basement apartment has electric colors, exposed ceiling beams, and decorative throw rugs. There's even an at-home movie theater for your little ones in an Airbnb basement apartment. If you have a son, you may want to invest in an inflatable Play-Doh!
