-Where did you spend your holidays?
-I... in a summer camp
in town
in the countryside
by the seaside
...

Ну, возможно этого и хватит для ответа на вопрос, а может одним предложением нужно было. Для запаса вот несколько. Более открытый ответ на вопрос. --------------------I spend my holidays by the seaside with my family. It was a fun trip, we were walking near the seaside, taking a lot of pictures. It's sad, that the summer is over, I really would liked to go back to the beach and the gorgeous see. Also I was in a summer camp, where I have found lots of new friends and learned a lot from everyone.
