Should the idea of being gently rocked to sleep take your fancy, check in to Paris' first floating hotel. The sleek, 80m-long catamaran-design structure moored by Pont Charles de Gaulle sports sun terraces overlooking the Seine, a chic bar with silver beanbags by a 15m-long dipping pool, a lounge and 58 stunningly appointed rooms and suites, some of which have Seine views.

　　There's live music on weekends.
