Stop looking and just book this little gem!
The studio is a terrific little getaway and is very true to the photos. It is a studio, so it's not huge, but the space is well planned out and there's LOADS of space to put your stuff (big closet, drawers, nice bathroom counter).
The location is ideal if you have a car (or rent a bike). You're a quick hop to the shops and tourist traps on Ali'i Drive (free parking wasn't too hard to find), you can walk or drive to Ali'i Gardens Marketplace which is worth a stop, and if you want a quick dip or to watch the sunset you can walk a mere 5-7 minutes to the beach just down the street. You're also an easy drive arrive from several beaches.
As for the area you're in, it's a neighborhood. You will hear the neighbors during the day (nothing annoying, just your basic human activity), but it's nice and quiet at night, and there's even a little park just up the street. The studio itself feels very private as it's tucked away at the back of the main house (where the host lives).
About that host...she's terrific! She lives on-site so if you need anything, have questions, or have any trouble, she's readily available. And she's easy to talk to while giving you as much privacy as you prefer.
The only downside was the studio doesn't have the best air flow, so you're not getting those pleasant trade wind breezes that usually keep things cool. As such, it can get pretty stuffy, especially at night when you close the door. There is a fan and a ceiling fan, which did help, but if you're super sensitive to heat (as in medical-condition sensitive), you'll want to keep this in mind.
Still, overall a great place, great location, great host, and I wouldn't hesitate to stay again.
