I love twin beds...in a guest room...or in a small child's room. If you are over five feet tall, it's just not comfortable to sleep in a twin bed for more than a few nights. However, if you are trying to maximize sleeping space (for people that might not want to sleep in the same bed), then this is the perfect choice for your guest room. The symmetry of the two beds facilitates some very dramatic designs. I especially love the fabric canopies and exquisite headboards in today's inspiration!
