Input: Had to bring my new puppy with me on a business trip and stayed at the Palmer House. The service was wonderful, staff was very friendly towards dog owners, even stopped to tell me how nice my dog was. Easy access to red line from Midway. Valets were prompt at retrieving car (they recommended calling down in advance we did and the car was there waiting).

Output:
positive
