I came to Honolulu for a conference and needed a comfortable place to spend my week. If you're travelling alone or with one other person, I highly recommend Ash's place. It's a corner unit that overlooks part of downtown and when you wake up you can see the mist rolling in from the high ground at the center of the island. Plenty of TV channels to choose from, reliable Wifi, and the kitchen and bathroom were immaculately clean. I really can't think of anything that I would change even if I lived there permanently!
Check-in and check-out were extremely easy (even though I got in pretty late) and the location is perfect if you want to see Waikiki. It's a really easy walk to get to the beach, there's plenty of ABC stores, restaurants, and a few bars within a 5-minute walk. If you need to get to other parts of the island, there's a smart car rental in the lobby area, and a few other chain car rental places down the block. Kind of hard to find parking in the area (as expected for Waikiki) but there is a parking garage attached to the building.
Building is well-maintained and had no hiccups during my entire stay. Whenever I'm back in Oahu, I'll definitely be looking to stay here again!
