Traveled with my 8 year old son. I did not contact the agencies. Booking flights to Lufthansa and a hotel in Bucking. Then on your own to the visa center to submit documents.
Crimea love for a long time and go there to relax with pleasure! Nature, air, climatic conditions - everything favors a good rest and recovery! Believe me, there is something to compare with: Sochi, Cyprus, Italy, Spain, Bulgaria (by car), Egypt and Turkey.
