This is a lovely house in a great location, definitely suited for business travellers, friend groups and older families, with lots to like: nicely furnished, great space, nice back yard for bbq'ing, great sized bedrooms, 5-minute walk to Clovelly beach, and a really responsive, helpful host.
But, there are a couple of things I would check before booking:
It's not really suitable for young children. The mezzanine level is a falling hazard (there are lots of signs up), and if your kids like to climb (like ours do) you'll spend a lot of time watching them and making sure they're not anywhere near the railings.
There was no internet for our entire week stay. It was not a case of there being internet and it was patchy. There was none. If WiFi is important (business, kids iPads, etc) then double check with the host if the internet is actually fixed before you book (the problem apparently is in the street), as this was debilitating for us.
As I say it's a great house in a great location, but check the above if those aspects are important to your stay.
