Kitchen Hearth Room Help Needed :

Hi....These are pics of our hearthroom/kitchen area. The area is pretty small and I am design challenged. I don't have much room so I can only buy things that I really love or that are cheap enough for me to re-do and get rid of when i get tired of it, therefore I find myself not doing either. I have tried a couch in front of the fireplace but it was too large and i have tried a couch in front of the windows and table/chairs in front of the fireplace. The couch covered too much of the view of our water feature in the backyard. Shoud I do a loveseat?? I am not married to the table and chairs. I could paint or replace?? My husband did the beautiful stone work on the fireplace which I love and I painted the walls and built-ins recently and am pleased with the colors. I would love your suggestions?? Thank you so much.
