Gertrude Mary Davis

My great grandmother Gertrude Mary Davis left some notes that said she was born at No 1 Auckland Terrace Douglas. I cant find an Auckland Terrace in Douglas. She said it was 3 stories high and had a attic at top. Smugglers cove underneath – a passage led down to Smuggler’s cove on shore.
Can anyone identify where in Douglas this would be
