Think once more. As I understand there are risks in taking furnished accomodation. It has to be clarified as to who will take care of repair in case of any failure. For items such as sofa/table etc, there is a possibility of getting cheated.
In my opinion, you can purchase all the items at a less cost, when you compare the furnished and unfurnished accomodation.
You can start with the minimum items and then go on additing items.
all the best
