Are there any unique boutique hotels in the Keys?

Key West, the largest island, is renowned for its unique historic architecture and never-ending nightlife around Duval Street. It offers endless places to visit, including the Ernest Hemingway Home and Museum and the magnificent sunset view at Mallory Square. The Overseas Highway connects all the islands, and the whole drive is a treat to the eyes as you can witness the fantastic azure water and thick mangrove forests.
