Tommy’s place is great and with perfect location. It’s close to everything you need for your stay in Kailua. Place is small, good for a solo or a couple, has all the things you need - i stayed for almost 6 weeks as a solo traveler. I spent most of my days outside anyway!
Keep in mind there’s no washing machine, so you’ll have to drive in Kailua town (3 mins away) to a laundromat which I personally didn’t have any problems with.
This is the place I’m booking again on future trips to Oahu!
