Our reading
An editorial interpretation.
The speaker gives an uneasy response to a place, choosing the cumbersome word “uncomfortableness” to name it. That phrasing can add a comic awkwardness to the admission. The source of the discomfort remains unstated, so the emphasis falls on the feeling and its unusual expression.
