Hotels & Accommodation near Jaywick Martello Tower

I made the booking on behalf of a disabled mother and her 2 twin daughters in my role as her trustee using funds from her disabled person trust fund. I complaint immediately at arrival, the situation got worse when the host accused the guest of trashing the caravan without any evidence and refused to refund the deposit. The guest took pictures at arrival to proof that the caravan was so filthy you could call it inhabitable. The smell was so bad they felt unable to breathe without leaving the door open. The sofa was too dirty to sit on and most of the bad odour was coming from the sofa. The cooker was rusty, shower had sand & mould. The curtains were on the floor, the beds were covered in stains and hair. The carpets were badly stained, mouldy and the fridge and all appliances’ surfaces were dirty. I believe that the pictures I've posted speak louder than words (and in case the host is disputing the date they were taken, they are date stamped). The guest was not in a position to afford to book alternative accommodation for 8 nights with her children and did not want to ruin their holiday by going home, so she had no alternative other than trying to make the best out of a very bad situation. You can only call this a clever scam, offer rather cheap accommodation in a very bad state, accuse the guest right from the beginning of lying and withhold the deposit to make more money. Probably when the next guest arrives this scheme will start again. AVOID!!!!!! TERRIBLE!!!
