"for bookings before june 15th the 4th night is offered" a native english speaker may find this incomprehensible. but any continental european would understand what it means. native speakers are frequently at a disadvantage since they do not allow for the same flexibility in the interpretation of words as 2nd/3rd/4th language speakers of english do. especially if they're monoglots, as most native english speakers are.
for the disadvantaged native english speakers in this world of "english dominance", the website does add a helpful translation: "Book your stay before June 15th and get 4 nights for the price of 3" -rishab
