There is a safe in every room, very small... however, there is a manager's safe.
My mom had some important documents (passports, etc), and she doesn't really trust the safes in our own room. So we called the front desk and asked if they have any bigger safe there, turned out they have "manager's safe". According to my mom and my wife, the manager's safe is VERY secure, that it has several locks and require different set of keys, and nobody knows where it's at. Even the manager had a hard time opening it, apparently we are the second people who requested using it within 7 months (since they installed it).
