Escape from the maisonette

You just knew that it was not worth to book a room at this hotel. Even reading the bad reviews on their personal website, you knew it was a bad idea, but too late to be sorry about anything. You have already locked in their room, leaving, of course, not a single key. You need to carefully look around and see if there is nearby objects that will help you get out of here as soon as possible. Good Luck!
