Finding somewhere to stay in Sydney over New Year is always going to be difficult/expensive. We found Micky's place in April 2019 and booked it. It wasn't cheap at 250 UKP/ night (1,500 UKP for 6 nights) for 3 of us staying but nothing was at that time of year.
Initial comms from Micky was good. Welcoming and helpful. Bit of a problem regarding checking in on the day as we asked for comms via email not website as we didn't have access to websites on our phones..... didn't being laptops/iPads while travelling.
Location is good. Easy to walk into city. Good access to buses. Plenty going on in the area. Pieno cafe on the corner was really good and had breakfast there most days.
Disappointment was the cleanliness (or lack of it). The house needs a really good clean and there is no excuse for this of you are renting out your house. I took quite a few pictures (if they can be uploaded into ABNB). General dirt, dust, cobwebs and insects.
Checking out was also a problem. No instructions. No response to email the night before we left. Couldn't access keysafe to leave key. Neighbour (understandably) didn't want to take key so had to leave it under a pot in the unlocked courtyard.
Improvements needed before I could recommend Micky's place.
