Guest cancelled at last minute due to a mixup in the expected check-in times, despite us being willing to work out a resolution. Her initial listing only stated a checkin time of after 2pm, however she subsequently sent a message 1 week before our arrival stating a much tighter checkin window from 2-3pm. Due to a system glitch I did not receive the message until she sent a follow-up message asking where we were after we missed her narrow checkin window. We were on the train to Florence from Rome when she messaged us that she asked Uber to cancel our reservation because we missed her check-in time. She was very anxious and imbalanced in her reaction to the situation and strikes me as someone that is very controlling and rigid. I would not recommend booking with her based on the way she handled the cancellation and refused to give a full refund or acknowledge her role in creating a situation that could have been avoided had she been willing to work with us.
