We totally recommend Charlies apartment because you have everything you need for a city trip! The best is the central position! You have lots of shops around, metro stations and can even easily walk everywhere, to sights like Sacre coeur, the Opera, la Fayette, moulin rouge...we even walked to Champs Elysees , the Grand Palais and la Tour Eiffel. Although we didn't met Charlie, he prepared everything perfectly for check in and check out. We had a good time! Thanks for having us Charlie! :-)
