The apartment is quite a bit older than it looks in the photos, but was spotlessly clean. Unlike some similar offerings, it had enough space for two to have a comfortable stay. It has a separate kitchen with a decent sized fridge (very unusual), and a separate toilet. Some thoughtful touches, like a power board for plugging in computer, phone chargers etc.
A couple of issues only: It was unusually cold for Sydney, and there was no heater. The host promptly answered my email, and a (very small) heater arrived quickly. It was enough to see us through. Also, the only two chairs were an armchair and an uncomfortable low stool. This could be easily fixed. The kitchen has no table or bench suitable for eating. The only table is in the small alcove, where even two would have a tight squeeze if they wanted to sit together for a meal.
The host obviously monitors his emails frequently, and answers any concerns promptly. Overall, a professionally managed property with excellent communication.
