Yes, old standard practice: put the thermostat in the hall but don’t attenuate that radiators output. I have today had a new boiler installed and modern practice is to keep the thermostat in a room that is well used. I can move mine around, it communicates with the boiler by radio. So you can experiment and find the best location to give you the room temp you require.
As I posted above, my boiler died on the coldest day, surrounded by snow. My usual engineer who installed the boiler and has serviced it has retired, so I got a new guy and his first act was to persuade the installation engineers that two old people would die of hypothermia unless they worked their day off. Result, we are warm as toast.
