The property requires wireless or wifi connection in order to use the application which gives you access to the property location's building door. This is not something an out of towner like myself had available resulting in my having to wait a long time to have a resident of the building give me access inside. I should not have had to depend on a building resident to enter the building. Also, the fact that wireless or wifi access is needed to use the application to enter the property should be informed in the check in information or property listing.
