Private Space (Kealakekua, HI)

Hi, My name is Dee! Looking for a space near (within a Bike ride, if possible) to Kona Community hospital, as I will be on assignment there for a contract.
Will be finished with contract and going back to mainland March 30th.
I require Nothing but space I can safely leave my belongings without getting stolen.
While in Oahu on contract, I stayed in a small shed built into a carport.
I am looking for something similar.
If I need to set up My tent to make it work, that would be just fine.
I am trying not to pay more than $400 a month but that is negotiable.
I have plenty of Hawaiian and mainland references, available once I am contacted.
Shoot me an email! Thank you!
