Two bold pop-art studios. One unforgettable duplex. The Green Pop and Yellow Boom! sit side by side in the heart of Sofia — each with its own bedroom, kitchen, and bathroom. Two couples, two friends, one family: stay together, sleep in total privacy. No shared bathrooms. No sofa beds. Just two fully equipped studios with designer interiors, a private balcony, and Serdica Metro steps away. Sofia's most colourful address — and its most practical one.
