I'm sorry, but the guest didn't arrive at the announced time, so we left him a message to ask him to tell us when he was arriving. But he had no wifi, none sms or phone at all. So we had to go every half an hour to check if he had arrive yet. It was quite strange his delay because he already was staying in a hotel in the city before his arrival. That was the first time we had a problem with a guest arrival. Every body else is satisfied and even we usually let to leave the luggage inside the apartment before the chekin time.
The guest didn't respect the rules of the apartment. The AC works very good. And it's reasonable to use it if it's hot, like many of the days of his visit, really hot days. But it's not ecological, respectful with the neighbours and reasonable to use it everytime, even when he was not at home or during nights it was less than 25º.
I had many others guests this summer, around these dates, who used the AC every time it was needed without problem. But they were respectful with the rules of the apartment.
Anyways, communication with the guest was very difficult because he didn't answer the phone, he had no (Hidden by Airbnb) or messages, he didn't even answer in the app. Problems can be solved with a good comunication but he didn't seem to want it.
First bad experience in more than 45 guests.
