We had a very good stay at Charles's apartment in Rue Bichat recently. Its very close to metro stations like Goncourt, Republique, Jaques Bonsergent and international one Gare Du Nord. Its very well maintained flat comfortable for a family/group of 4-5 people. there are many restra/bar/groceries nearby. Neighborhood is quite peaceful. Charles is very helpful and easily reachable for any information/guidance you need in Paris. Whenever visiting Paris next, will prefer staying here again.
