@Sally550 You can log into your account from any device anywhere. But if you aren't going to be available to answer guests in a timely fashion, you can snooze your listing, which means it won't appear in search, so no one can see it or book it. Then let your already booked huests know that you won't be available to answer any messages until XX, but not to worry, you'll answer as soon as you get back.
You don't use a smart phone at all?
