Please stay at Aïda's place! Not only is she a great host, but her place looks even BETTER than the photos! Aïda is super communicative and helpful. The area around her apartment (near St. Martin canal) is great - lots to do, lively, great ethnic shops around, and the Metro is easily accessible by walking or by bike which is nearby. I have stayed in many places around Paris, and Aïda's place scores at the top!
