If you're looking to spend most of your time in Hawaii outside (and not inside your room or your hotel, like with the Waikiki resort complexes) then this apartment will do the trick. It's definitely not luxurious but has the basics and is in a great location. It fits 2 people but more would be cramped.
You can hit the beach in as little as 5 mns walking or get to central Waikiki beach in 15-20 mns walking. It's also easy to catch a bus to visit something outside Waikiki. There is a convenience store nearby, as well as several breakfast and restaurant options. The apartment has a small kitchen with cooking utensils but we ended up mostly eating dinners out.
David was courteous and likely very knowledgeable about the area but we didn't ask him for suggestions, we ended up just using our guide book.
Overall if you want to experience Waikiki without spending a fortune or being pampered, this is a great option. Mahalo David!
