We have come up with a nice modern design for your wall and made a sketch of it in the furniture scheme. Along the sketch is a list of pieces we think would suite your style along with your existing furniture and a scheme of colours, we believe blue would look nice in the space with the beige toned modern furniture. The curtains we found are available at : https://www.amazon.com/Exclusive-Home-Wilshire-Burnout-Curtain/dp/B01HHA5QZY with shipping to italy, the lighting can be found here : https://famio.co.ke/blog-10-simple-light-fixtures-tips/ ; and the main wall is custom made of wood and brick slips.
