Extended StayAmerica generally requires guests to be at least 18 years of age to book a room. However, it is important to note that specific policies may vary by location. Some Extended StayAmerica properties may have additional requirements or restrictions. This typically means that guests under the age of 18 may need to be accompanied by an adult, or additional identification and consent may be required. It is advisable for guests to check on the specific location they are interested in, as policies can differ. For the most accurate and up-to-date information, visiting the official Extended StayAmerica website or contacting the specific property directly can provide clarity on their age restrictions and requirements.
