Grunewald is part of the ‘Villa Ring’ of southwestern Berlin, an area of luxurious single-family homes dating from the 19th century, many of which are now designated historical landmarks. Embassies and cultural organisations occupy a few of the Grunewald villas, but the vast majority of them are owner-occupied single-family homes. The families who live in Grunewald are primarily those of doctors, professors and business executives. The section of Wilmersdorf closer to the city offers accommodation quite similar to that of neighbouring Charlottenburg: large, attractive Altbau flats. The average rent is €7.34 per square metre, and the average apartment purchase price is €1,650 per square metre. The average rent in Grunewald is €9.77 per square metre, the highest in Berlin. Houses for purchase in Grunewald cost an average €3,800 per square metre.
