Great serviced apartment style room in the Ilikai Hotel building - fully equipped with kitchen (with fridge), balcony and living area. It was super spacious and very comfortable. It's an older building but super clean. You check in with the resort (note as stated in the description, there is a daily resort fee) and the staff are very friendly and helpful! They let me store my luggage before check in and even stored it for a few hours after I checked out.
You have access to the pool and other facilities. There are various shops on the ground floor including cafe, restaurant and convenience store so it's easy to pick up food. There are also some restaurants across the street/a couple of doors down from the resort.
Whilst there is a beach and lagoon nearby (near the Hilton, which is next door) there is no direct beach access from this
Note that this location is a little bit further away from the centre of Waikiki Beach (about 1-2kms) so you either have to walk or take the Bus (the local bus company). The immediate neighbourhood is relatively quiet compared to the hubbub of the Waikiki Beach centre.
