Second, think of ways to create more storage space. This is crucial in a small apartment where there's not a lot of room.
Third, consider getting expert help. Having someone come in and tell you ways to maximize space can save you a lot of money, and grief, in coming years.
Finally, reduce clutter. This is the biggest killer in a small apartment. Clutter makes a small place look even smaller. Less is more.
