This flat provides a wonderful base from which to explore Paris. The Pompidou Center is on your doorstep and there are many cafes, restaurants within easy walking distance. You can walk down to the Seine and see Notre Dame in only about 10 mins.
If you are traveling by Eurostar the nearest train station is only one stop away by the RER from Gard de Nord so it is all very convenient and easy to navigate.
Franck is a great host and made us feel very welcome.
I recommend this as a base for exploring Paris.
