Dear Yanhong, this is very unfortunate but I am afraid that most of the incoveniences have been caused by you. I offered to send you a taxi I work with to bring you to the appartment, you refused, mentionning that the hotel taxi was free. Mine wouldn't have costed you much, it would actually have saved you a long time driving around. I told you I couldnt welcom you myself and told you where the keys would be hidden for you. I never mentionned the guard, I even wonder why you bothered him. I also told you where the mailbox key would be hidden, you would have taken three minuts to read my SEVERAL emails, you would have saved three hours. The appartment has been clean just before your arrival. I am actually surprised that you have any idea of the concept of "clean" seeing the absolutely disgusting state you left the place after your departure, without mentionning the four aircon that you have left ON, running for days, as well as the lights that you didnt bother turning off as well. ABout the supermarket, maybe you should have looked around, as there is one litterally five minuts WALK from the appartment, the second closest one is five minuts drive. and about the beach it is thrity seconds away. I have no clue how you managed, the only thing I am certain about is that I will never for any good reason host you again. You are part of the people who make the experience airbnb terrible.
