A+++ location! half a block from the beach. One pain for us was looking for parking but that's pretty much anywhere in the Waikiki area.
Shannon's place is super clean and comfortable to live in. Also has a small kitchen with kitchen utensils if you want to bring back food or fruits. The unit is right above a grill and bar so it gets a bit noisy at night but didn't bother us since it was a great atmosphere, and the folks seems to be respectful and tend to stop being noisy around bed time (10~11pm ymmv).
Shannon was also very responsive to questions, and the convenience keyless entry is you don't have to carry a key around to the beach! (that might get lost)
Highly recommended for anyone looking for an affordable place close to the beach without the hotel/resort fees
