The communication from the host was not the best. It should have made clear from the start the water was not safe to drink. We had a couple of glasses of water before we were advised, which in turn made us sick for most of the weekend. I would advise going to the supermarket before you arrive to collect essentials.. bottled water, coffee, milk. We arrived on Waiheke island at 8pm and everything was closed. If the water is not drinkable a few bottles in the fridge would have been a nice touch. I also found it strange to have a coffee machine but no coffee pods or milk.
We were also advised we could leave our luggage in the garage after check out, as we planned to spend the day on the island and it had easy access. When it came to check out we could not access the garage and the host never responded to our message of how to access.
The place itself was very nice and views were stunning. If these things were communicated it would have been a very different trip.
