Dan's place is centrally located just north of Honolulu proper in the Maikiki area. It's about a 5- to 10-minute walk either east or southwest to hit a major transfer line for the busses into town. The area itself is quiet and quaint, having good amenities and being well-positioned for easy access to the H1 to get you around the island if you're renting a car. And it's an absolute steal for the price.
Unless you're looking for something more scenic like a North Shore or somewhere deep in one of the valleys, you can't do better than Dan's!
