Stayed at Karl's for 3 days to start off my trip in Maui. The self check-in was PERFECT for me as I came off a late flight. The room can get noisy from traffic and people outside, so definitely bring earplugs. The washroom is clean but dated. Not much in walking distance so you'll need to drive for food and groceries. The location though was a good 10min from shops, the Kihei boat ramp, and restaurants. Great place to stay for a few days.
