For a nightlife-focused stay, I’d choose somewhere within easy walking distance of the main entertainment areas. I came across
https://hotelx-au.com/ and it looks like an interesting option if you want a more stylish boutique atmosphere. Being close to the Valley makes it easier to head out for drinks, live music, or dinner without worrying about transport late at night. The Calile is another option worth checking if you want a more polished luxury experience. Personally, I’d compare the location and room style of both before booking.
