 A room without a window is called a cupboard It should not even be legal and definitely not called a 4 stars hotel And when there is written on the booking description that the room has a view not having a window is a consumer fraud Eventually when a hotel mistakenly charges GBP 267 instead of 297 one can expect the customer to be informed that a mistake was made and that an additional GBP 30 will be charged before the additional charging happens
