We have a mixed review for The Roost. We loved the location, kind host, excellent recommendations for the area, superb sheets, and plenty of towels. The house is beautifully situated in the woods, but we recommend future guests bring ear plugs (it's located just off SH1 and the traffic noise is disruptive before 5am).
There are some areas that could use more attention such as some musty odors in bedrooms, mice (I know, it's fall and the cooler nights send them indoors), broken outdoor furniture, and some cleanliness issues. I feel that had we paid less I would have let those issues slide...so maybe it was a lower value than I had expected.
Regardless, we enjoyed our 3-night stay and we got to do the hiking and fishing we wanted to in the area. The host is amazing, she thoroughly answered the questions we had about visiting Turangi and Tongariro ahead of time to ensure we would have a good stay. I hope she'll consider our constructive criticism to make The Roost even better for the next guests.
