Miami beach hotel advice

Appreciate advice on a hotel in Miami. Would like south beach, good location, not too loud. Hoping to keep it under $400/night. Art deco would be nice, but not necessary esp if it means smaller rooms or old infrastructure. The W was highly recommended but it’s a bit pricey.
Thanks

Eden Rock (you can walk down to south beach easily and far enough away from the craziness. Good restaurants there and next door at Fountainbleu as well).

Both nice and very elegant. Also depends on when you’re going. A lot more action and noise further south you go from 16th.
