This stay was very stressful and scary. Another guest was given the same door code by the host and entered the suite in the middle of the night (there is no inside lock/deadbolt) while my mum was sleeping.
This guest also continued to disturb my mum (and me, once I arrived), would not leave and continued to loiter in the common space outside the door. I eventually moved my mum out of the suite in the middle of the night as she did not feel safe staying there and the host would not resolve the problem.
I noticed that another guest has left a review about a similar door code experience/issue (in November 2021).
