You can basically make a mix with Metod and Platsa, a dresser below and a wall cabinet above, and that way you have the key storage and still lots of storage space. If you leave a bit of space (30 cm?) on the left side of the plan, where the largest contiguous area is next to the bathroom door, I think it works. The front door leaves enough space so you don't immediately bump into the side of the cabinet there. And on the top right of the plan the bench, as you mentioned.
