Had a lovely quiet and relaxing time here. the apartment is below the main house and has its own entrance. very spacious, nice small kitchen and host provided some eggs and milk as well. there is no oven, but a microwave and stove top which is perfect for a couple of nights. the bed was very comfortable and the fireplace kept the place warm and toasty.
it's a short 8-10 min drive into healesville and bit further out so the wifi could be a little flakey but overall i had no issues and was able to use their Netflix roku in the evenings.
the only potential consideration is that the upstairs portion of the house where the hosts live has floorboards and so you can hear the footsteps as they walk around. personally didn't have an issue with it but it could be a something to consider if there are light sleepers.
The interactions with Kristoff and Beata were easy and they were very accommodating.
overall, i had a lovely time and would consider them if i went back
