We spent 2 nights in one of the cottages in mid Feb and had a wonderful time. The hosts are incredibly friendly and do everything to make you feel at home and at the same time as guests. They even looked after our baby while we played tennis with their son (don't be fooled by the fact he is only 7!) and afterwards shared their dinner with us.
The cottage is spacious, clean and private and there were yummy brownies and beer in the fridge! The breakfast is also pretty substantial and delicious.
In response to the guy who complained that it is not actually in Greymouth - well, it's better this way and it's usually a good idea to check things on the map to make sure the location satisfies your needs. For us it was perfect.
