Waiheke is a beautiful island. Buses are frequent and bus stops very close to Frankie's place so you don't need a car. Seahorse has a lovely outlook over the garden and has everything you need for a short stay. Quiet and relaxing. Nearest supermarket and restaurants in Oneroa about a 25 minute walk (uphill on the way back) but short bus trip. Plenty of car/scooter hire if you want to see parts of the island not covered by bus service. Didn't use kayaks or bikes but lovely to have the option.
