Answer:
A wonderful holiday I have had
(A brief description of the holiday )
Last month, we went to Erbil to spend our holiday. I went with my parents, my sister and my two brothers. We stayed at a nice hotel in the city centre. The place was very nice. I like it so much. During the day we used to visit the nice places there. There are a lot of parks and malls to go shopping. We visited Erbil Citadel and the high mountains which are covered with snow. So, I took a lot of photos. In the evening we used to stay in the hotel because the weather was cold. We had dinner and watch TV. I used to play video games till late hour. The best thing about the holiday was the hospitality and the nice treatment of the people. But the worst thing about the holiday was the very cold weather.
