What a marvellous location have the farm and the cottages. We stayed for 3 nights in the Rata cottage. Perfect for us. If you want a bigger cottage or 'hang' over the water I would recommend one of the other 2.
It was lovely to sit outside sheltered from the wind. Elspeth went out of her way to accommodate us with some special things. She even saved our laundry from getting wet again. A lovely person. The cottage is in between the Abel Tasman Park and Nelson. We would not have mind to stay a lot longer in this peaceful environment. And...great restaurants in nearby Mapua!
