We stayed at Lia's place for 4 nights, and loved it. Our plan was to have a place in Waikiki so we'd be able to be within walking distance of a lot of stuff, but also to be able to explore the island. With this apartment being right in the middle of Waikiki but also with an included parking spot, it was perfect.
The apartment itself was fantastic. Location-wise, it was a block away from Kalakaua Ave, making it super easy access to the main drag and beach but without huge crowds right outside the building. We had no problem walking around to get to things in Waikiki, though it's far enough from Ala Moana and Chinatown that we generally drove when heading out there. It was an easy and pretty quick drive to get to the highway when we wanted to get out of town.
The apartment itself was perfectly furnished for my wife and I - we kept the bed pulled down our whole stay and had plenty of space. We had everything we needed for our stay, including more food and cooking accoutrements than we had expected, plenty of toiletries, and a ton of beach equipment including snorkeling gear that we made constant use of. Getting in and out was easy with a lock that we were able to program a code for ourselves. I also cannot say enough about the amazing view from each of the lanais. Overlooking both the ocean and the skyline, it was incredible to wake up to and to watch the sunset from.
Finally, Lia and Steve were fantastic hosts, who were very responsive, met us on arrival and made us feel very much at home.
I'd highly recommend this place if you're looking for somewhere to stay in Waikiki - we absolutely would stay here again if and when we return!
