Without a doubt, location! It is perfectly located right in the heart of Sydney within walking distance to almost everything, and very well situated for public transport and shops.
The apartment was very secure and private and well equipped to meet all your needs. The decor is a little dated, but the apartment is clean and comfortable and I would recommend it.
Zak was very responsive and helpful in his communications answering questions I had and offering suggestions, and flexible about check in/out times.
