Anyone have their kids sleep on a different level in the house?

I currently live in a 5 bedroom bungalow. I have 3 bedrooms on the main level and 2 in the basement, which is perfect. However, we live in a crowded neighborhood and have a small yard. We recently found a home very similar to ours on 1.5 acres of property. We love everything about the home except for the fact that their are only 2 bedrooms on the main level. There are 2 bedrooms in the basement, but my kids are only 2.5 and 1 month old. For now, my daughter is sleeping in a bassinet beside our bed, but when she is around 6 months we planned to transition her to her own room in a crib as we did with my son. I just would not want to have my son in the basement sleeping at 3 years old. We really wanted to make this home work but I worry about the bedroom layout. Anyone else have this issue with your home? Any suggestions?
