Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: This was a great hotel right in the heart of the Chicago Loop. Within walking distance to the downtown attractions. Parking is expensive ($50 p/nt) so we parked at a free remote location (recreation drive) since we weren't planning on driving once we checked in. The staff was friendly and helpful. The rooms are large and clean.

Output:
positive
