It's easy to communicate with Federica. We emailed her before our arrival & when we got to the 5th floor outside her apartment, she was there waiting for us. The place may appear plain, but it has everything we needed for a comfortable 2-night stay. Federica went through & explained everything (I love the old map she used to show us directions). A gracious host, she kept telling us to contact her for any need. Rue de Sentier is very quiet, but with less than a hundred steps we reached the very French Rue Montorgueil. It has restaurants of different cuisines, groceries/supermarkets, fruits/veggies/meat & fish stores. As we kept walking, we reached the Church of Saint-Eustache where we attended 6pm mass in French. Across the Church is Nelson Mandela Garden which is currently under renovation. Right underneath is Les Halles Metro Station where we returned on the day of our departure to take the train that goes straight to Charles de Gaulle Airport. Other attractions can easily be reached by bus or metro. In fact, we walked to Musee du Louvre in 15min. Everything is perfect for us. My only regret is our stay was too short for an eventful Paris & more interaction with our lovely host.
