The beach is about 5 mins walk way from his workshop and there is a really nice cafe pretty much where you'll arrive at the beach, if that makes sense (The Secret Beach Bar & Kitchen). If you hit the beach and turn left then there is a nice promenade that will take you into town (c. 30 min walk). Or you can go the other way and walk right around the bay to Mumbles.
The job only takes a few hours though, so expect to get a call around lunchtime if you drop it off in the morning.
(Edit to add: it's a really nice sandy beach by the way, not a horrible rocky/pebbley one)
