Discover Cosmopolitan Hotel & Spa. In Paralia Katerini, next to the beach, in the shadow of Mount Olympus, we created a modern hotel, built in aluxurious, contemporary Mediterranean style, designed to offer our guests affordable luxury and convenient service, combined with the finest principles of Greek hospitality. The sandy beach is just a short walk. With its natural harbour, traditional tavernas, open-air markets, cafes and bars, Paralia Katerini is very popular with both Greek and foreign tourists attracted to the beauty of the coastline, making it as one of the best-known parts of Northern Greece.
