We came to the apartment at night to find out there were already other people in there. They had the door back locked and Gary didn't answer the phone. Gary had accidentally given our door code to people who had booked another apartment. Luckily, even though the other guests were freaked out by us trying to open the door (as we didn't know they were in there), they eventually opened and gave us their doorcode in exchange. If they hadn't, we would have been totally without a place for the night. Gary didn't answer our numerous calls before the next day, and even then it seemed their biggest concern was how it will mess up their schedule that we switched rooms with the other guests. Also, it was a bit unpleasant for both of us guests live in an apartment knowing that there are other people who also know our doorcode and could enter the place when ever we're not there.
Otherwise, the apartment was clean and nice.
