 I had an ongoing problem with the electrics lights in the room The first night all lights and power switched off including telephone had an engineer in the room for 30 mins with a torch trying to fix some lights worked others did not the bathroom lights flickered continuously so were really annoying Engineer back again next day then in the evening while having a bath all lights again went out as system tripped Finally resolved while I was out for the evening and when I came back to the room the empty boxes from the engineers spare parts were left lying in the room
