The apartment overlooks a lovely courtyard and is very quiet. It's just a 5 minute walk from the Bastille, one of the liveliest and enjoyable neighbourhoods in Paris. There are plenty of shops, cafés, restaurants, bakeries and wine cellars. There is a great Farmers market at the place Aligre, just 2 minutes away where you can stroll around and feast your eyes on the beautiful produce brought in fresh every morning.
It's also very close (2 minutes) to the rue de Lappe, a very fun street with tons of bars.
Not far (10 minutes), you can reach the Gare de Lyon, Paris gateway to the south of France, just in case you may be tempted to take a three hour trip to the Côte d'Azur on a high speed train.
There is also plenty of transportation available to get around Paris. The metro station at Ledru Rollin will take you directly to the Champs Elysées, both Operas, the Galleries Lafayette and the Eiffel Tower. There are also plenty of buses to whisk you around the capital.
If youd like to see Paris by bike, there is a Vélib bike rental stand nearby. It's a great way to visit the nearby Marais or the Latin Quarter. If you are coming by car, underground parking (you will have to pay) is available just across the street.
