My dream room. Wow, let's start with the interior I would like my room to have delicate pastel ocher wallpapers, on which I would hang posters of my favorite bands. My room must have a balcony with a table and two chairs. It will be decorated with different flowers and in the morning I will have a cup of coffee there. There will be a large round bed in my room, there will be a work table on the side, a dressing table next to it, a small table. Opposite the tables will be a wardrobe, vast and full of different and interesting outfits. There will be many plants in my room, and I will stretch a bright yellow garland across the ceiling. This is the room of my dreams
