Thermostat is under lock and key and they set it to heat insufficiently. I complained several times. Nevertheless, I caught cold because of it just prior important meeting. They claimed to fix it, but problem persisted which is when they cited local laws about city imposed limits on heating. I lived in Rome for two years just down the street from them... there is no such law.
Clearly the owners are more worried about limiting their bills than their guests health.
Bad experience.
