Ixelles or Elsene is an extremely pleasant neighborhood of boulevards, squares, and a string of lakes known as the Étangs d'Ixelles. Is divided into two parts by Avenue Louise, which is part of the City of Brussels municipality. The smaller west part of the municipality includes Rue du Bailli/Baljuwstraat and extends roughly from Avenue Louise to Avenue Brugmann/Brugmannlaan.

The larger east part of the municipality includes the sites of the Université Libre de Bruxelles and the Vrije Universiteit Brussel, and the Eugène Flagey square. The Bois de la Cambre is located just south of Ixelles.
