Sheryl's charming house is located in a nice quiet area a bit outside of the city but it is really easy to get to Queen St by bus. One Tree Hill is in walking distance (20minutes) and if you wanted you could even do a part of the coast to coast trail, walking through the quite streets of Auckland, passing One Tree Hill and arrive to Mt Eden Summit after an hour, maybe an hour and a half depending on your pace (and another hour or so walking to the city center).
Sheryl is a nice and natural host, always ready to chat and give recommendations but never forced. She even provides some tea, Coffee and Toast for breakfast which is a big plus.
The house was clean, the bed comfortable and the room nice.
Definitely recommend staying with Sheryl!
