Definitely an old building that was remodeling in an affordable way to be picture ready. Possible mold/mildew. I had the window cracked but it still messed with my asthma and smelled musty every time I entered the unit. The location was to die for. I had to stand outside in the cold for 30 minutes trying to get inside because the door code they supplied me with didn’t work. After being hung up on once I finally got inside with a new door code.
