I have no regrets choosing newtown as the place of my stay. Youthful, vibrant and artistic neighbourhood. There are many choices of food on the King Street; many murals or graffitis here and there; less touristy.
Although there are some uphills here (I hired a manual wheelchair for my dad and it's hard to push it uphill), I have however observed that sydney does have many uphills anyway. There are many free parking spaces here but they can be really narrow and be taken up very quickly at night.
The house itself is awesome, very well maintained and the descriptions and pictures shown fit very accurately. No misleading. House is beautiful. You can find everything you needed there. Lots of utensils, spices, toilets rolls, washing machines, etc
Importantly, the host has Netflix! So you can literally Netflix and chill in the house. I can't express how excited I was when I saw it.
Host also ensured smooth check in and checkout and is indeed very kind. The only downside is that there was problem with radiator (it's really cold for us especially when we come from tropical country) but he immediately offered some discount after I informed him.
In short my time in the stay was good. I enjoyed it.
