We both had an amazing stay the the Buxton House and really loved the Scandi-styled interior. Very clean and minimalistic! The place itself was cosy in the back of the house - it is an elongated kind of area, so could be quite hard to get things moving around. Nevertheless, we made it around comfortably.
Neighborhood is safe, albeit hearing stories about walking at night around Refern. We had no troubles walking back to the apartment at about 11pm.
There are lots of coffee and food options opened in the day and Buxton House is really close to Sydney Central with various methods there. Really loved the place and would definitely stay again when we're back in Sydney!
