Apartment Hunting

We continue in our search for our new apartment. We have now looked at almost a dozen potentials in our neighbourhood. some of them are very large, others are very expensive. We have recently narrowed teh search to three potential places. Apartment A is expensive, but HUGE. Apartment B is less expensive and just a hair smaller. Apartment C is well designed and cheaper, but smaller. The difference in price between A and C is roughly $500 bucks a month. Between A and B is negligible however, we get a parking spot inside the building's parking elevator. Neither A nor C have parking available. Both B and C are about 5 minutes walk from the subway. A is 1 minute from the subway. I'm leaning heavily towards Apartment "?" which do you suggest? Should we keep looking?
