Our wee bach at Whangamata has a studio-type floor space: 2 single beds, a bunk bed (double below, single on top) and multiple mattresses. All linen is supplied. There is a fully equipped (tiny) kitchen with stove, microwave, and fridge/freezer.
There is a separate bathroom with toilet and shower facilities. The bach is walking distance to the local supermarket and to the central township. You can walk to the beach, but we usually take the car.
It's nothing flash, but has the basics.
