Hotel du Jeu de Paume

If you've never had a chance to discover Ile St. Louis, it is a particular side of Paris within Paris. First of all, it is the oldest inhabited area of the city, and at one point was referred to as the 'island of cows.' That was centuries ago, though, before the aristocrats of the kings' courts moved in and built their grand, stately mansions. Today, it is populated by tourists and locals alike. There are only a few hotels in this 'heart of Paris' neighborhood. This one, particularly, is a landmark, since it still houses the oldest tennis court known in Paris. Legend has it that even King Louis XIII used to come and play here.
