I've stayed with Sheryll and Dave before while in town for the Cycle Challenge. I wanted to book with them again this year since I had a great stay with them the first time.
Sheryll and Dave's home is convenient to central Taupo and the Marina. It was great for getting to and from the Cycle Challenge start and finish lines.
Sheryll and Dave are very friendly, accommodating people. They are great hosts and people to stay with.
I'd strongly recommend that you stay with them.
