New Year's weekend, my gf and I stayed at the Bentley (referred through a super friendly and helpful broker).
The Bentley is a 4.5/5 star 3-star hotel. It's not super fancy, but has all you need if you're looking for great stay on South Beach. Friendly and helpful front desk. Awesome location (5th St. on Ocean Ave, on the beachfront, at the southern end of all the Ocean Ave / Collins Ave' restaurants and attractions -- the bigger hotels and the shops on the Lincoln Ave promenade are at 17th st). There's a great sandwich deli place around the corner, along with Walgreens for beach supplies. We had a delicious dessert late night at the Bellini (the Bentley restaurant), which was very relaxed (and warm).
The ocean is a four min walk across the beach. The pool / hot tub on roof was good for a quick a dip; the sun chairs for a relaxing, tanning afternoon away from the beach (even though you're still overlooking the beach).
The room was your standard type room with small kitchen, small balcony, comfy-bed, small couch, tv.. perfect for sleeping in, showering, chilling in, but not lounging all day in. But, you're in the heart of SoBe so why would you want to be inside (all day) anyway.
