I have stayed for a month in Ash's apartment. There are pros and cons as always. My overall opinion, it was a nice stay. I recommend it. But, know the pros and cons and decide for yourself of course.
Pros: Ash's communication. He was super easy to reach out and fast replier. The location was superb. Easy to get every popular location in Sydney. The city view was amazing from the apt. I've had always felt safe during my stay. There is also a concierge during work hours. The open pool was fun. Dishwasher tablets and paper towels were a nice gesture.
Cons: Noice. It is hard to sleep after 8 am. There was always an ongoing construction around the apartment. The main elevator wasn't working during my stay. I had to use the goods elevators which are shared with the hotel workers. Sometimes I've waited for 10 minutes for the elevator. It was a real pain to use it. The kitchen amenities were dirty when I've arrived. I had to wash them again.
Nice-to-have: A small pack of snacks would be nice to have. I've arrived at the apartment around 8 pm. It was really hard to find an open place at that hour in the city center.
