May we introduce ourselves?

Our slogan "Come as a guest; leave as a friend" is not just an empty phrase. Many guests already experienced the truth in this statement after a great stay with a feeling of leaving friends behind.

The sincere friendliness and "care-free" attitude of the local people is the key to that special experience.

Most staff members have personally helped, some for 16 years or more, to build Thalassa to what it is now.
