Sounds perfect! I lived alone in a flat with a balcony close to a big park for years with my cocker. We were very happy
A show cocker, though in theory more docile than a worker, is still a clever and sporty dog and they still need to get both mental and physical exercise every day as I'm sure you know
So she should have time for at least one proper walk and a little mental training. In my experience show cockers adjust well to our lifestyle as long as they get plenty of attention, and it sounds like that will not be a problem
I have always heard that the boys are much softer than the girls in this breed. But I only have experience with girls, red girls to be presise, and they have all had a bit of a temper towards other dogs. They've all been lovely and cuddly and trainable, but a little bossy around other dogs. I've had some trouble with doggie sitters due to my girl not gettiing along well with other dogs inside. Outside is fine, but inside she starts resource guarding everything from other dogs. It's odd and probably not common, but it's always good to plan for what to do
if your dogs don't get along.
Anyway, I'm no expert, but it sounds like a good life for a cocker. And it sounds like your daughter is lucky to have so many people to help her out
