In the short years since the castle's renovation, its popularity has boomed among holidaymakers. Guest now have the opportunity to book out the entirety of the castle – Stef and Simon have relocated to a cottage around a 10-minute drive away, but are always on hand to help.

Kilmartin has become something of a destination for small weddings and elopements, while the couple has also started a secret supper club at the estate for guests and locals, curated by local chef William Hamer.

The cherry on top of the castle's success came in 2022 when it was named the 'hottest property' in the independent UK and Ireland accommodation sector at the 2022 Eviivo Awards. In January 2023, Kilmartin Glen and the castle itself were even singled out in The New York Times' '53 Places to Go in 2023' list.
