As a returning guest last Alex's place, I booked for one week. We both didn't realize that the booking was only until Saturday on the website but understood between each other that I was checking out on Sunday. When on Saturday morning Alex realized that I hadn't booked for that night, he was kind enough to offer the last night of my stay as a present - when when I offered to pay. I was worried and felt bad for not having realized the incorrect booking but It was such a convenience thanks to Alex! :D
