Typically we aren't ones for boutique hotels. We like our hotels modern and minimal. Boutique is hard to do well without an enormous budget and the corresponding ridiculous nightly rates. Unique period, or design, pieces are expensive; the lack of mass production is what makes them. Thus the attempt at boutique comes off as gimmicky, a cheap impression of the real thing.
Thompson Miami Beach however is a case study in how to do reasonably-priced boutique hotel. Attention to detail, spending on specific pieces while ensuring the in-between pieces still fit seamlessly, is what makes it work.
Two full size pools, an in-house restaurant with an excellence dinner service, and direct beach access give you all that's need for a few lazy days by the beach.
