We stayed three nights, starting the day off with a jump into the clear water of Golden Bay (just walking through the garden to reach the beach), continuing with walks in Able Tasman or along the sea shore. The apartment has an incredible view and all the amenities you need. Fiona and Nev and super nice hosts, giving good pointers on what to explore.
Don't miss out on Mussels Inn, just a few km down the road. They might have some live music while you enjoy their home brews.
