The best way to make a small space look larger is to avoid the tendency to add in too much furniture, or make it too large-scale. You need pieces that offer you enough seating, but with smaller profiles in both your living and dining space. Look for multi-functional pieces with storage, keep the wall color the same in areas that flow together, and use the walls for vertical storage and display instead of relying only on freestanding pieces. Look for furniture retailers that advertise "apartment size furniture," and see Houzz Photos under "small space living" and "vertical storage? for ideas. You can use art, an area rug or similar to decide your color scheme. Your apartment really isn't that small, fortunately, by big-city standards.

Price is not a function of design. It depends on the finish n material. You should specify what your budget for a stone top dining table set is.
