We arrived late and went straight to bed, but woke the next morning to find our bathroom flooded from an blocked and overflowing toilet. Staff were good, they came straight away to wash out the room and fix the toilet (obviously a common fault as they came armed with a large plunger), but they only used water from the bathroom basin to flush the overflow down the outlet pipes, no disinfectant!!! Also the entire floor (we were on 5th) smelt badly of mould.
