the meaning of 'and'
The passage below comes from The Glass Castle By Jeannette Walls.
https://books.google.co.kr/books?id=opdvCefTFngC&pg=PT13&lpg=PT13&dq=%22The+hospital+was+clean+and+shiny.+was+white%22&source=bl&ots=m_rcEIkSjA&sig=gsySrB3XKrgMh1nqR9tKdVBfUJ8&hl=en&sa=X&ved=0ahUKEwja3ceg87zKAhWE3KYKHfkcAdIQ6AEIHzAB#v=onepage&q=%22The%20hospital%20was%20clean%20and%20shiny.%20Everything%20was%20white%22&f=false Everything was white—the walls and sheets and nurses' uniforms—or silver—the beds and trays and medical instruments. Everyone spoke in polite, calm voices. It was so hushed you could hear the nurses' rubber-soled shoes squeaking all the way down the hall. I wasn't used to quiet and order, and I liked it. I also liked it that I had my own room, since in the trailer I shared one with my brother and my sister. In this passage I'd like to ask two questions regarding this passage.
1. The meaning of the underlined 'and'.
It seems to mean 'but' because the meaning of the clauses before and after the AND is in contrast to each other.
As far as this meaning is concerned, FreeDictionary shows 'and' can have the meaning of 'but'.
http://www.thefreedictionary.com/and 9. but; on the contrary: ? He tried to run five miles and couldn't.
Am I right or is there something important that I miss?
2. Can I remove the underlined 'it' in this case?
In my sense of grammar it's OK.
But I want to make sure about that.
Regards.
