Before booking we agreed with Nineta that we will arrive only at around midnight since our plane is landing at Catania at 20.00 and it is around 4 hours to reach Trapani by car. Also, Nineta wrote in the listing that check-in is ok any time after 4pm. Nineta said it is ok so we booked the room. At the airport we had some trouble with the car rental, so we wrote a message to Nineta at 21.30 that unfortunately, we will arrive only around 1.30 after midnight. She wrote back that sorry, but she can't let us in at 1.30 so we can't check-in. We started discussing in chat that how can we solve this issue. Nineta was really refusing, said straight no to our all possible solutions what we came up.
At the end of the day, Nineta left us on the street for that night, we slept in the car. On the next morning, she offered a half refund in case we still don't want to check-in at her listing. We accepted this offer and booked another apt in the city.
You should be aware that Nineta is really unflexible with the check-in time before booking a room in her apartments.
