It’s currevtly nearly midnight and I can’t sleep. I am staying with my daughter away from home as we visited my other daughter at uni today. We are staying in a very clean and comfortable room in a sort of unmanned hotel/guesthouse in a residential area as I couldn’t afford the prices of the hotels on the city centre.The reason I can’t sleep - the macerator toilet keeps making a loud grumbling sound every minute or so, it’s really loud, even with the bathroom door shut. Sounds like it might be faulty. My daughter next to me is fast asleep luckily. Do you think this is grounds for requesting a refund?
