Personal belongings disappeared from my room. I spent one night here on an event. In the morning I went to the hotel restaurant to have breakfast. When I got back my swimwear, flip flops, phone charger and handsfree were missing. These were all the things that I left on visible places like the table and the bed. I turned to the hotel employees for help but they didn't seem to be sympathetic to the problem and said they don't have a way to track back if someone has entered the room while I was at the restaurant. I'm just glad and lucky that I didn't leave something more valuable in there.
