The sign on the building says "СОЛАРИУМ," which is Cyrillic for "solarium," pointing towards a country like Bulgaria. The architecture and the overall urban feel are characteristic of Eastern Europe. The yellow diamond-shaped road sign indicates a priority road, common in many European countries. The weather looks overcast and cool, consistent with the region. I am fairly confident this is in Bulgaria.

The Cyrillic script remains prominent, confirming my suspicion of Bulgaria. The overhead power lines and the style of the buildings are very typical of Sofia's suburban or semi-industrial areas. The overcast sky and wet pavement suggest a damp, cool climate common in this part of the Balkans. I see a billboard that reinforces the local context. I am now quite certain of the location.
