We stayed at the Ohana studio for two nights as it is close to the volcano park.
The building(s) are inside a secured yard and has a password protected entrance gate. There are multiple guest units in the yard. Clear, picture instructions were provided for directions and check in.
Upon check in, we needed a few things like paper towel and garbage bags. The hostess responded quickly and brought us what we needed.
There is one step/ stair from the room to the bathroom. Be very careful at night.
There is AC in the room which is a bonus.
