This was a fine location as we explored Abel Tasman.
We were 4 adults (mom, dad, daughter and her husband) and found the space just fine for our needs and, in fact, better than anticipated based on reading some of the reviews from previous guests.
Annemarie was very helpful ... she even purchased some groceries for us when I realized we'd be arriving on a statutory holidays and therefore stores would be closed!
We would highly recommend Annemarie's place. The second bedroom is bunk beds (shown in the photos, I think), so just be aware of that. Our newlyweds were OK with this set up as they're quite accustomed to hostel stays.
