I didn't really panic when I saw the first cockroach. After the second one around 11 pm, I went to the front desk to ask for another room. The receptionist called the owner, who asked the receptionist to verify that there were, in fact, cockroaches.
When we got back to the room, there were cockroaches all over. I got my stuff packed and sat in the reception area, hoping that they had not gotten into my suitcase.
Apparently, the owner wanted to put me in another room in the same area of the hotel - their reasoning was that no other guests had complained about cockroaches, so they must have been only in that one room. At that point, I would have preferred to sleep in the lobby and started looking for another hotel, which was not easy, as it was already midnight.
The receptionist expected a call from the owner to make a decision. At around 12.30 am, the receptionist decided that the owner was asleep, so she moved me to another room in the main building, which seemed to have no cockroaches.
