I don't know how big your family is, but even when I was on my own with a tiny stove like this I did just fine and I did quite a bit of cooking on it. You won't be able to put as much in the oven at once, but it will be easy to adapt your meals around it once you get used to it.
Is there no room to put a bigger stove in it? Or is this a rental where you can't change anything.
As I say, it takes some thinking if you are trying to do a big dinner (Thanksgiving, etc.) but you can become creative with doing things differently. Also, maybe looking into a toaster oven will help - you can even get convection ones for a good price these days.
Good luck and have fun with it.
