do not stay at an airbnb unless you have access to email and or a smart phone when you are travelling. Important information such as how to access your rental apartment may not be available to you, causing the need to contact airbng direct to get in touch with the owner to get the entrance information to you. Not a good situation to think you might be straded outside your rental with no way to contact the renter if your do not have your email or a smart phone.
