Small but perfectly formed is a good way to describe the cottage.
Nice view, really close to the lake, great wifi and superb communication by Kaz all made for a great two-day break.
There's not much in the way of cooking facilities but the Lake Hawea Store, Sailz Restaurant and the hotel offer really, really great food so you won't want to cook. The burgers at the store are exceptionally good (better than BurgerFuel) and we had great, reasonably priced dinners at both Sailz and the hotel.
The cottage is super close to the Lake Hawea cycling/walking track. We hired bikes from the hotel and really enjoyed cycling to Wanaka and back - the Albert Town to Wanaka stretch is one of the prettiest rides I've ever done.
Kaz was also generously flexible with our check in/out times.
