Response from Mayumi:
This lady changed the check in time 4 hours earlier on the arrival day.
I had my work schedule impossible to change at last minute so basically I was running late. She did not go out because of me she had a dinner event with someone and that was the reason why she decided to come early which was no problem, after her arrival I stayed there for another hour to get out.
If my place was that dirty and I was dishonest I would have not received so many nice reviews. I enjoy my guests coming from all over the world exchanging interesting conversations. However, be ause everything was so rush I accept I might have left some spots to clean. I will take more time to check if the place is clean throughly before I leave.
