Example Input: We have just returned from 4 nights at the Conrad Chicago, everthing about the hotel was excellent. Wonderful room and service from all the staff was first class. Great view from our room. The hotels location is great, right in the centre of the magnificent mile. A wonderful stay in an amazing city was made perfect by our stay at the Conrad.

Example Output: positive

Example Input: We were disappointed with this hotel. The staff seems hurried and unhelpful. Our room was not made up until after 5 PM despite several requests. The blower in the hallway blew freezing air, but the staff told us that there was nothing that could be done about it. The lobby is not inviting and there is no where comfortable to sit. The room and bed was comfortable, but the cream and and modern art work are not our style. The room lacked many of the amenities other hotels in this price range offer. Certainly not worth the rate compared to other hotels I have stayed at in Chicago.

Example Output: negative

Example Input: Very friendly staff - and helpfull with whatever ? you may have. Don't miss the wine bar and the hot chocolate bar. Spacious rooms. Perfect for business and for theatre guests. A little quiet area during weekends.

Example Output:
positive
