The place was very nice, clean and spacious, everything you might need was provided. Chifumi was very responsive and accommodating. The only downside is that you can hear all the noises from around the house - it's not a big deal since it's not a busy street, but you can hear people talk late at night or early in the morning.
The location was good - not in the main Waikiki area, but walking distance. Close to safeway and a few restaurants and cafes (Happy Haleiwa has great acai bowls!). Walking distance to Diamond Head as well.
