The home should be reasonably close to a hospital in case of a medical emergency. A large home may have more activities while a smaller home might be more personal. Decide which is best for your needs. Often the best arrangement is one that allows visitors to come anytime. Make sure you find out what extra costs are involved in addition to the basic daily room rate.
Some homes only provide the bare minimum in the way of services.
You do not need to feel committed to your first roommate. If you are dissatisfied, see if you can change. Also, see if you can bring some of your own furniture. Ask if they reserve a bed if you need to be transferred to a hospital. Medicaid will pay for 7 days of bedhold.
