Lack of hot water

Day before had phone call from owner informing me that the room we were allocated has a toilet problem and we might have to be re allocated a downstairs room if the problem not sorted, luckily it was. Shower and sink in room kept loosing water and were not warm. Mentioned to owner the following morning and was told they would be sorted. Arrived back after day out to a written note on how to keep water running and warm, but it still wasn’t warm and was water was stopping mid use. Mentioned again at breakfast to owner for any other guests. Owner mentioned that staff levels were down. Breakfast was really nice and fulfilling, staff were very friendly and chatty.
