We stayed for 2 nights in fern cottage 1. The accommodation is very nice and modern, comfortable bed and sheets, good bathroom and it's clean. The wifi was almost non existent it was so bad. The tv was embarrassingly small, and it didn't even have the Channel with the Olympics. Also the cereal that was included was an already opened, half eaten box and was expired by 2 months.
It's a fine place to stay, but the feeling is this; for $160 a night it is overpriced for what you get. If you are a couple I would say there is more value in a b&b. but I definitely recommend staying on the otago peninsula, great place.
