Dan was incredibly helpful by text message before getting to the island - and in a very relax manner too, often some airbnb hosts can seem a bit formal via text!
The Bach/ unit is secluded but very pleasantly so. A tv with Netflix (and a good wireless internet connection) and a surprisingly brilliant kitchen meant everything you need but nothing to overcomplicate a get away from hustle and bustle.
Being secluded, remember to bring some stuff from a supermarket if you plan to use the kitchen inc coffee and other small bits. We only stayed one night and if we had to get up and leave for breakfast stuff (which we got the day before) it would've meant missing out on a chilled morning in a beautiful place. Personally, I wouldn't travel out for breakfast with this view to enjoy...
Taxis...very expensive so plan on island travel wisely (note this shouldn't be a negative on the review as dan is not the taxi owner!). The buses are good, and a $10 day pass is pretty reasonable ay?
We ate at wild on waiheke which we would also recommend - beer, wine and reasonably priced food.
