I had a condo that was 1200 sqft. but it was 2 floors, each floor being 600 sqft. The bottom was open: kitchen, dining, living room. The top floor had a bathroom, laundry and small bedrooms. It really worked well. With the downstairs being one room with 600 sqft. wide open it felt large and spacious, sociable. Upstairs was more functional (as in you didn't spend much time there) but also made it cozy enough to retreat or read if you wanted. EDIT: having large window and minimalist furniture helps.
