We really enjoyed our stay at May's place! It was spotlessly clean and fresh. we found the bed very comfortable and the range of pillows available was great. The kitchen amenities were perfect for what we wanted (simple breakfasts and afternoon tea).
The chalet is located at the back of May's house, so you park next to her house and go through waist high gates to get to the chalet. The property is on the main road, but being set far back from it means the traffic noise is minimal. (There isn't much traffic anyway!)
We walked all around Bicheno from May's place - its in a great location! And Freycinet National Park is only a 30 min drive away. I definitely recommend going there while you're in Bicheno!
