We were in Sozopol from July 23 to August 2.2015, we took a ticket at the travel agency "Albena Travel". This was the first trip to Bulgaria and hopefully not the last as Sozopol is amazing.
Rested in Sharm, at the hotel "Hauza Beach Resort" the first week of October. The hotel was chosen, as they say, from what it was, because the ticket was bought 3 days before departure.
