It won't be hard for me to describe my room because it's my favourite place in our flat. Obviously, I spend there most of my time. It's a perfect room for me because I designed it myself. I can't say my room is big but it's not a small one either. Anyway, there's enough space for all the neccessary furniture. When you come into my room, the first thing you'll see is the bed. It's very big and comfy. Despite sleeping in it I enjoy watching movies on my laptop while sitting on the bed. There's a bedside table next to my bed. I usually keep there a few things that I need to have when I go to sleep and in the mornings - phone, a bottle of water, some hand lotion and a good book. I can't forget to mention the closet that is quite big as well. I store there all my clothes and bags. Finally, there's a chair and a table. Sometimes it gets messy though I try to keep everything in place. I spend a lot of time in my room and never get tired of it because I'm just used to it and it's the best place for me to study and relax. Для меня не составит труда описать свою комнату, так как это мое любимое место в квартире. Конечно, я провожу там бОльшую часть времени. Эта комната идеальна для меня, потому что я сама придумала дизайн. Не могу сказать, что она большая, но и не маленькая. Так или иначе, здесь достаточно места для всей необходимой мебели. Первое, что вы увидите, зайдя в мою комнату - это кровать. Она очень большая и удобная. Помимо того, что я здесь сплю, я также люблю смотреть фильмы на ноутбуке, сидя на кровати. Рядом с кроватью есть тумбочка. Там я храню вещи, которые нужны мне перед сном и утром - телефон, бутылку воды, крем для рук и хорошую книгу. Не могу не упомянуть шкаф, который тоже довольно большой. В нем я храню одежду и сумки. Наконец, в комнате есть стул и стол. Иногда там беспорядок, хотя я стараюсь держать вещи на своих местах. Я провожу много времени в своей комнате, но она не надоедает мне, ведь я привыкла к ней и считаю ее лучшим местом для учебы и отдыха.
