I fell for Bulgaria fast. Sofia feels rough around the edges. Plovdiv is artsy and slow. The coast is warm in summer and the mountains stay cool. People are proud of their food and folk music. Most travelers enjoy the easy blend of old churches, street art and tiny taverns.
For nomads this works well. Cost of living is low compared to Western Europe so your money stretches. Internet is mostly fast and cheap. Cafes and coworking spaces have steady wifi. Mobile data works across cities and mountains. There are live nomad meetups in Sofia and Plovdiv. For some, that will be amazing. For others, the scene can feel small town.
Things to do are wide. Hike Rila one morning. Sip wine in a village the next. I read online about a beach volleyball group near Varna. I showed up and joined. It felt local. Bulgaria is honest, simple and easy to explore. You might love it. Or you might want more city buzz.
