I need help to choose my first backpack

I am looking for help with choosing my first backpack. I want i backpack that is sleek and not to bulky. Main features i would like are separate laptop sleeve and water bottle holders. Max price I can afford is like 185 to 200 dollars. I found a backpack that I somewhat like and it is alpaka metro backpack pro, but it does not have water bottle holders. Backpack does not need a lot organization and it should not be to big, around 24l to 26l. It is my first backpack and I do not know much so any suggestions would be very helpful. Thanks in advance.
