The lock was broken when we arrived, which we didn't realize at first. On the second day, however, the inside door knob fell out, into the room, and prevented us from getting in. Luckily, I was able to open the door anyway. But it kept breaking in various ways for the rest of our trip, locking us in the room on the day we wanted to leave, which made us almost miss the train because it took 15 minutes to figure it out, and locking us out of the room when we tried to get back at around 1am another day. All fine, but I just imagine that guests who are not a heart surgeon and former boyscout might have a had a bit of a less agreeable experience—perhaps even panic. *Everything else* was great!
