Guillaume's place is fantastically located, within walking distance, you have the Louvre, the opera, Place Vendôme,Les Tuileries and the Jeu de paume museum, Le palais royal,the left bank and the latin quarter are no more than 15 minutes away
There are plenty of very typical french restaurants open late very close to the apartment, and the area is very lively, bakeries open @ 7 am and bars are open way past midnight.
Rue Montorgueil next door to the apartment has plenty of shops and a market where you may buy everything you could need . The kitchen is well equipped
We highly recommend Guillaume's apartment
