Checkmyguest is putting guest safety at risk. There is no key available to the door, and access is enabled via a weblink. This link was faulty during my entire stay, leaving me stranded outside after midnight with no access to the flat or my belongings. Checkmyguest has no emergency numbers functioning, and has failed to respond to our emergency for the entire stay (4 days). We had to resort to having security break-in via a window to access our belongings. This company should be removed from Airbnb. We had a terrible experience of customer service, and they even wanted to charge us over £2500 for repairs without taking any responsibility themselves for their security failings. Any responsible business would either have an alternative key or an emergency telephone service, and will not solely rely on faulty web-service for guest entry.
