I think I am certainly quite late to reply on this post but nevertheless will put my suggestions here. Go for 2 loveseats in a light/neutral colour against the 7 ft and 15 ft wall. Opposite the 15 ft wall you could put a nice upholstered bench in contrast/printed fabric. Also for a warm glow put a nice standing lamp in the corner between both sofas. You can place a nice mirror on the TV wall and put a nice shelf beneath it and place a lamp there with few knick knacks if the door opens outside in the balcony or is sliding. Also, keep two upholstered ottomans below the mirror which can be pulled for extra seating when required. Place a low height coffee table small one like a 2x2 ft.

this is my living room suggest me wall paint and ceiling paint colors
