We were staying at Apartment One in March for 6 days and enjoyed our time there a lot! The apartment seems to be newly renovated and is very stylish. It is perfectly located, in Darlinghurst, in the middle of the city, yet on a quiet street with many restaurants to choose from just minutes away.
The staff was very helpful and straightforward when it came to check-in and -out times and everyone was extremely friendly and nice all the time.
When we come back to Sydney, we'll definitely return to Apartment One.
