The 1BRs in Kidani have a pedestal safe in the master closet. I don't know what kind of safe is in a Kidani studio.
Here are a few photos from a Kidani 1BR showing the front of the safe, a medium sized laptop in the safe and a standard 8-1/2 by 11 inch piece of paper as a size reference:
Just a reminder, these types of hotel safes are easy to get into if you know what you are doing.
Plus, there is a default, "master key" combination which is probably known by at least half the hotel staff (I would go off that assumption just to be safe). The code might even by all zeros if no one bothered to change it.
Consider all of this when you decide what to leave in there.
