The apartment is large, with a well appointed kitchen, if you're into self-catering (byo coffee!). The location is great, in a residential apartment block on a side street but really close to buses, a biki bike station (share bikes with pick up/drop off stations throughout honolulu), and only a block away from waikiki's action!
As other guests have mentioned it's pretty noisy throughout the night, so bring earplugs/ not recommended for light sleepers! Saichi is a good and helpful communicator and very prompt to reply, and check in/out is super easy.
