That's what I would do. Actually, I would probably go ahead and go to the AirBnB in most cities but it's a long, expensive ride to the city from KEF. I do not handle jet lag well so getting sleep would be a priority. I would look into lounge access. I've been all over KEF but really didn't take notice of sleeping possibilities. Personally, I would take a xanax (or melatonin if you don't have a prescription) and get as comfy as possible to sleep on the way there.
Some people can get 4 hours of sleep and then force themselves through the next day, you have to ask yourself if you are one of those people. Me, I get really disoriented, have headaches, and just cannot function so I would catch as much rest as I could.
