Input: Stayed at the Sofitel Chicago Water Tower for 3 nights in early April 2007. Very convenient location just a block from all of the shopping on the Golden Mile. Good restaurant at the hotel serving a la carte breakfast different from the usual fare and with a nice French twist. Dinner at the restaurant was also good. Prices are reasonable. Room is comfortable, only problem was with a card access door lock that usually required several swipes before opening. Excellent service from the bellmen to the concierge and front desk staff. Would definitely stay here again if visiting Chicago. Concierge recommended a small van tour, which was excellent. However early April is too early to visit Chicago as popular activities such as the boat tour of the architecture of Chicago was not operating yet.

Output:
positive
