For value for price, this little retreat tucked away in the mountains is so worth your while. I scoured the area for the best places near Mount Dandenong and the Yarra Valley, and this place offers value far and above everywhere else, and the cottages are so nice. We stayed in the Gateway Cottage, and it was amazingly charming and intimate. We loved the character of the cottage, and the fact that it had a double shower and a huge bathtub for two looking out into lush gardens was of course a perk. With the capacity to make a cooked breakfast along with freshly made bread in the morning made it even better. It was super cozy both for a summer or winter getaway, and it's a great launchpad near Olinda. The only downside with the cottages is that neither my wife or I had cell reception, and the cottages don't have Wifi (though the apartments in the main building do), but this might be right up your alley. Would definitely stay again.
