There was no heating in the room and so, the technician said he would turn off the AC in the room and we should wait for the room to heat up naturally. It was 16 degrees, how was the room going to heat up. I asked to speak to the manager and he showed me some other rooms, of course with the same explanation. All rooms were cold. After insistence they provided us with a space heater. This is a 5 star hotel and escalation for temp control should not have to be escalated to a manager, it should be a line protocol.
