With their crystal blue waters and white sand beaches, the Florida Keys provide the perfect setting for couples' getaway. And for the love-birds looking for a truly intimate stay in the south, these boutiques know just how to set the stage for a magical time. Come take a look at some of the most romantic boutique hotels in the Florida Keys! The13-room Conch Keys Cottages is located on a tiny private island a short drive from Marathon and the Keys' airport. There’s a small but beautiful beach (not swimmable at low tide), free kayaks, and a nice outdoor pool (though there's little space for sunbathing). It offers a relaxing and low-key stay, especially for couples looking to kick back.
