Flat for sale 3+kk • 97 m² without real estateKastellweg Heidelberg Neuenheim Baden-Württemberg 69120

For sale is a spacious and well-proportioned 3.5-room apartment on the first floor of a well-maintained residential complex in the highly sought-after Heidelberg-Neuenheim. The apartment was previously rented to a family of physicians for eight years – it now stands empty, was freshly painted at the end of January 2026, and is available for immediate move-in. As the owner is professionally based in Freiburg, the apartment is being offered for sale.

With 97 m² of living space, you will enjoy a thoughtfully designed floor plan that is ideal for couples or a family with one to two children. A true highlight is the 12 m² balcony facing west, accessible from three rooms. Here you can enjoy wonderful evening light, while the apartment’s orientation keeps it pleasantly cool even on hot summer days.

The building is surrounded by a huge, park-like communal garden of over 3,100 m², featuring a sandbox and plenty of greenery to relax or socialize.

Flooring: Parquet floors in the living areas

Kitchen: The fully equipped fitted kitchen (standard), including electrical appliances (purchased in 2017), is included in the purchase price

The apartment is located at Kastellweg 10 in Neuenheim – one of Heidelberg’s top locations. The University Hospital, the DKFZ, the Mathematikum, and Heidelberg Materials are all reachable in just a few minutes on foot or by bike. The Neckar River is only a stone’s throw away.

Infrastructure for Families: A kindergarten is reachable in 1 minute, the popular Café Frisch in 3 minutes, and a large playground in 3 minutes. Mönchhof Primary School is an 11-minute walk away and Bunsen Gymnasium a 5-minute walk away.

The apartment not only provides a perfect home for owner-occupiers but is also an absolute premium investment property.

Standard Rental: A market-appropriate net cold rent of about €1,650 plus €100 for the underground parking space is completely realistic given the location and facilities. For a furnished rental, €1,700 to €1,850 can be achieved.

Special Permission for Short-Term Rentals:

A true rarity in Heidelberg! This apartment has an official short-term rental permit (e.g., for Airbnb) from the city. In the past, this has been very successfully used for international guest researchers. Potential net annual profits of €25,000 to €35,000 are realistic here.
