Fantastic location and quite peaceful given the proximity to all the restaurants, bars, etc. The place certainly has a homely feel when you arrive but is quite small and probably not suitable for any more than 2 adults without it being a squeeze.
Carolina has decorated the place in a very unique style which some may not fully appreciate. We didn't have an issue with it but our only suggestion would be to perhaps create the feeling of a bit more space by removing some of the ornaments if guests stay.
One thing to watch out for is the bedroom. It is a nice cosy space with a very comfy bed but the stairs leading to it are quite steep and narrow with no railing at the top to protect you from falling down the hole where the stairs present in the bedroom. If you had one too many wines, were elderly, a child or maybe a sleepwalker, you could easily damage yourself quite badly.
Others have commented on bugs, and yes we saw a few spiders and mosquitoes but this is what you get when surrounded by nice greenery in the back patio. A bit of bug spray (provided) sorted the problem.
As we are a family, we probably wouldn't stay again but it would be ideal for a young couple who want to be close to all the action Sydney has to offer.
