KIA lodge is just a short drive from the airport terminal. We had a long wait for a flight back to Nairobi, so we got sent here to chill for the day. I was pretty impressed.
This is a wonderful option if it suits your needs, though it's a bit far from the Arusha center. If you are looking to climb Kilimanjaro or similar treks, this may be an ideal spot.
There are wonderful views and very tasteful/ethnic decor, etc., complete with a pool, which has great views of the big mountain.
