Plovdiv, Bulgaria
During my short stay in Bulgaria for Doma Art festival we made a day-trip to Plovdiv, a two-hours-drive from Sofia, the city describe by many Sofiotes I met as "the most beautiful city of bulgaria".
Here you will find The DOMA Art festival Website and their Facebook-page. Please check it out as well, since their program is quite interesting and there are many things yet to see.
