People went to a hotel and they liked the room ' we had a nice room' - a hotel has many rooms and they are all different. They room they stayed in was in a collection of the better rooms. 'It was one of the best in the hotel' Maybe it was one of the best because it was bigger, or had a better view than the other rooms in the hotel.

When we visited Niagara Falls we had a nice room. It was one of the best in the hotel because it was on the top floor and had a wonderful view of the Falls. The rooms that were lower down weren't the best because their view was partly blocked by other buildings. Our room wasn't the VERY best because it didn't have a balcony. Some of the others had little balconies where people could sit outside and look at the Falls. But ours still had a perfect view, and the view is what you come for, so even without a balcony we had one of the best rooms.

Aha, I've got new several words about a hotel. :)

"one of the best in the hotel" depends on the standard of hotel. Normally, "the suit room" is the best room in the hotel.

Thank you!
