Pavillion de la Reine in Le Marais (not left bank) is perhaps another small interesting hotel in a unique Paris arrondissement.
Laurence, the owner of Esprit Saint Germain is a wonderful lady with a lot of charm and class. She has built a great team at her hotel. The only thing better than suite 101 is the ones with the small terrace. A bottle of wine out on that deck at sundown is a fun experience.
