The first rooms for rent were built in 1975 for Ravanis enterprise, but they were also the first in the whole region of Mt. Vardousia . Being a pioneer and visionary, Ioannis Ravanis, out of great love for his home, invested in this small, but very picturesque village, and people rewarded him.
Demand increased and the region of Athanasios Diakos (Mousounitsa) Fokidas gained in popularity through word of mouth.
A few years later he invested in the purchase and renovation of a second guesthouse to accommodate more than 60 guests. Ioannis Ravanis' love for his home was handed down to his children, so that even today, whoever finds themselves in Athanasios Diakos can enjoy the hospitality offered by him and his family.
