Как я и думал, ничем не отличается :)
Ответ отеля:

Dear Mr. Sviatoslav,

First of all, thank you for your interest in our hotel.
In our concept of Euphoria Aegean Resort&Spa, a promo room was named as a promo room for sales purposes but basically its is a standart room with land view.
If you have any further questions, we will be happy to help you.
We hope to see you in our hotel.

Best regards,
Euphoria Hotels
