All the reviews about the loveliness of the couple, the space and most importantly the cookies are to be believed. Great hosts and AirBnB.
Just a note about how hilly Government Road is if you are walking from town with heavy luggage. I was lucky to get a ride both ways from Diego (much appreciated) - if you are in a car no problem. If you are on the bus from Hamilton there is a stop very close to the house way before town so I would get off there. I was very overpacked in any case but hadn't thought about terrain only walking distance!
Also can recommend that at the end of the road the Yoga Barn is great if you are looking for a lovely space to practice yoga (5 mins away)
