We had a great stay at Jason & Kat's apartment.
Communication throughout was first class, check-in worked very smoothly and we loved the little brochure of tips and information in the room. We were able to check in early which was hugely appreciated.
The apartment is very much as advertised - if a little better in fact. It's compact but there's a lot of storage and it's well laid out. The view from the window is unbelievable! The bed was comfy, bathroom really clean and shower worked well. We had plenty of towels! The only minor issue for us was that noise from the street, even so far below, was surprisingly loud and the curtains are pretty thin so our sleep was a bit disturbed. But not a big issue.
The location is great - convenient for all the buses, beach, and the Waikiki brewery bar over the road does a great beer.
All in all we had a great stay, and I'd really recommend this apartment as a good option versus an expensive hotel.
