June 20 2023, check-in schedule at 18.00. At 17.30 we arrived at Belmont, already informed by chat with Travelio's cs. I was told to wait, because the check-in schedule was at 18.00. Alright I'll wait, because I think 30 more minutes, no problem and according to schedule. I waited until 18.45, and I called the person in charge in the field who wanted to meet me to give me the key to the apartment. I called, his answer was, I still have to wait another 30 minutes, because of a schedule conflict with another apartment, which, according to his information, had an appointment at 18.30, but at that time, the person had not come. Finally, we canceled to check in. When I was informed of the check-in schedule at 18.00, why wasn't I the first one? How much longer do I have to wait? Meanwhile, at that time, I needed to rest, because at night I had to continue my business trip. My first and last lesson, using Travelio. According to regulations, if a customer is late for 30 minutes from the check-in schedule, Travelio is not responsible. Well, now. What if the Travelio operational staff is late for more than 30 minutes? What is the response from Travelio?
