When it comes to moving a heavy fridge, it's important to find reliable help. A fridge weighing 160kg is a substantial load, and you're right in seeking professional assistance rather than a "man and van" service.
To make this process easier, consider looking for apartment moving companies in your area. They are often equipped to handle heavy and bulky items like refrigerators, ensuring a smooth and safe transport, even down a flight of steps to your cellar.
Additionally, you can explore online platforms where you can post your job and receive quotes and offers from moving companies or individuals experienced in moving large appliances.
