Stumped by ‘Indoor Recess’ Crossword? Here’s the Answer!

I’m sorry but the crossword question ‘Indoor recess is APSE‘ doesn’t seem to make sense. The word ‘apse‘ refers to a semicircular or polygonal recess in a building, usually at the end of an aisle or nave, but it doesn’t seem to relate to the concept of indoor recess. Therefore, without further context or information about the crossword puzzle, I cannot provide a detailed description of the answer. Could you please provide more details or clarify the question?
