Went to Warburton for a friend's wedding. Helen's place is situated in a quiet, uphill area of the town. (well, Warburton itself is a very quiet place) The rooms were kept very clean and I slept very well.
Both Helen and Chris were very friendly and helpful hosts, they definitely have the country hospitality.
The house is also very close to the venue space, Projekt 3488.
Overall, I highly recommend staying here.
