This "cabin" is a repurposed garden shed. There is a normal bed and a toilet and sink inside, but at the end of the day it's literally a shed.
You are directly in the flight path of the nearby airport and will hear planes flying over from 6am-11pm. You will hear them. I know it says that they've soundproofed things but it's still very audible.
Overall it's a fine, clean place if you are a college student or young couple just looking for a bed nearby little Italy and gaslamp. Barring this, you would be better off searching for local hotels which run about the same rate after all fees are said and done.
