Complete nightmare, I arranged 11am check in and when I arrived at the property was told the host didn't know what I was talking about and my check in was 2pm. Probably the most arrogant host I've ever dealt with, I kept telling him about our arrangement for 11am and he kept saying "I beg your pardon".
I ended up having to book another Airbnb whilst standing out in the freezing cold in London trying to find someone with an early check-in.
I do not recommend this host, no integrity whatsoever.
