This was a lovely, cosy, quiet place to stay, close enough to walk into Thames if desired (with a bit of a hill on the way back), and a short drive from lots of gorgeous spots. James and Robyn were very welcoming when we arrived and left us to enjoy our stay independently, with help on hand as needed. You have your own entrance with a key, so it really is like a self-contained accommodation rather than a room in someone's house.
The bed and lounge area were both really comfortable, with a lovely window seat to sit and watch the birds. The neighbourhood was quiet, the house on a quiet street. The accommodation is under the main house, but there were only the occasional floor creaks to remind us there was someone upstairs!
The driveway is curved and steepish. You can turn around at the bottom, but you probably wouldn't want to try in a big car or van. It was fine for my hatchback.
Site-seeing recommendation - we loved the Mahara Sculpture Park ($5 per adult, $2 per kid, cash only) and Raupara Water Gardens, both on the Tapu-Coroglen Road about 20 minutes from Thames. Mahara is just magical, and there's a lovely cafe at Raupara - I recommend the soup!
