At first I didn’t know how will I spend six days in Sofia, being unknown & not avery sexy destination, yet she managed to surprise me in few things: the food 🥘 – you can find a very good one at the Vitosha street on of the alleys, really good & cheap, the other is a pizza place/shop. And for sure visit the Vitosha mountain it’s nature at his best- claim or take the  cable car.
