Feel like taking a cruise but don’t want to leave the city? Try Paris’ first floating hotel, docked on the banks of the Seine at the foot of the Gare d’Austerlitz. Once inside, you’ll feel like you’re on a trendy ocean liner, especially as the music blasts when you are having a drink on one of the two decks that overlook the water. On warm days, you can even paddle in a narrow pool that separates the bar areas. The chic cabinlike rooms are small but well thought out; it's worth paying for a Seine-side room so you can gaze at the lights that reflect on the river at night. There's no room service per se, but if you pay at the bar in advance, you can have goodies delivered to your room.
