After trying to contact Melanie via email and Air bnb we finally got a response after 6 days, saying that our booking had been double booked and to look for other accommodation. If I hadn't followed up on this booking we may have landed in Dubai after a long flight and without accommodation. As we are elderly people this would have been very inconvenient to say the least. I will book through a normal agency in future and not through private people. Much more reliable. Very disappointed.
