Wow, can you explain how you did it? I tried to write ,,nice apartment'' HuggingFace link from stable diffusion, but I got this error: ,,This application is too busy! Try again soon''
With a prompt like this:
"ultra modern apartment, leather furniture, bold dark colors, built-in fireplace"
Add modifiers and other hints to see how it influences the outcome. You can add styles too (eg midcentury modern, shabby chic, etc)
Tinker with the settings on the right (note that most of them will burn more credits per image as you move from the default).
I've tried it with DALL-E and Midjourney and like the output of Stable Diffusion the best (specifically for this type of image, they are all good at some things and bad at others)
