Scrapy: сканировал, но не очищал данные

Question

Я написал следующий код для очистки Booking.com с указанием названия города. В идеале программа должна выяснить все отели, которые есть в городе, и вычистить все отзывы по каждому отелю. К сожалению, это скребет только несколько отелей и только первые 75 отзывов об этих отелях. Подскажите, пожалуйста, что я здесь делаю не так?
