Me and my friend we stayed for 3 days at Meera's place. She's a wonderful host. Every morning she prepared breakfast for us which included coffee, toast and fruit. A good start into day! :) also she picked up some bus plans for us.
The place is close to Koko Marina Center where u can get some groceries at Walgreens for example and there are some shops and even a movie theater. When we arrived Meera also took us with her to the Hawaii Kai Town Center which is bigger than Koko marina and where you have Costco and all the odds of a bigger mall.
The location is really nice. It's like a 20 minutes walk to the 1000 steps of Koko Head which I highly recommend but don't underestimate the steps. It's a different feeling walking up and to actually see what you have ahead. But yeah, there are also people who run this steps up and down. Just do it your own style! :D
Hanauma Bay: definitely go there. Don't forget to bring some money with you. The entrance fee is 7.50 for adults.

I definitely recommend this place. Meera is such a warm and giving person!

Hope this was helpful.
Have a nice vacation
