Midea's quarters are off of a small open square at the end of an alley. They are across from the area where Kai serves slop. Directly outside Midea's door is a table with a Nuka-Cola on it. To the left is a small area with a usable bed. There are two more usable beds across the square, in the room next to Kai.
It has everything that Midea would need to live. The bed is unowned and may be used by the Lone Wanderer. Notably, there are various food items in her home. Her house also has a filing cabinet with nothing in it that may be used for safe storage during your time at The Pitt.
