Pictures look great when using either SD 1.5 or Realistic Vision as the base model.
For some base models like Realistic Vision, the model seems to generate a lot of old-looking rooms. But if you want more modern looking rooms, add "modern" to your prompt.
Higher CFGs seem to work better, esp if you use "modern" in your prompt. Of course, it can depend on the rest of your prompt and your base model but a CFG of 10-15 would be a good place to start.
