And just to be clear, you are seriously, without jest, asking if 53 (you said the basement was 10 degrees colder) is an acceptable temperature to house a person? Seriously?

Op, do you keep your house at those temperatures to save money or are you comfortable at those temperatures? Is it because you find 63 comfortable? If so then consider putting a space heater in the basement so their space is warm and so you’re still comfortable upstairs.
If it’s to save money then I think you’ll have to be a hospitable host and raise the temps.
