Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:My husband, teenage son and myself stayed at this hotel last August. We were transferred there by tour operator who had sent us to a terrible hotel on the other side of Chicago. When I complained I asked for us to be transferred to the Sheraton which they arranged for us. I have stayed at many hotels in my life and this has been the best. The room (although I know it was not the largest) was beautiful and very clean with every amenity you needed. It also had superb views of the river and the lake. The entrance hall to the Sheraton is so imressive as is the leisure centre. In fact all areas are fantastic. The best thing about the hotel though was the staff! From the bellboy, to the receptionists, the dining staff to the concierge - each one was courteous and so very helpful. One of the conciergies spent fifteen minutes on the phone trying to locate a specific pair of trainers for my son! Above and beyond the call I would say! I cannot reccomend this hotel highly enough. The breakfast buffet cost about 10 dollars each but you could eat as much as you like and take as long as you like which we did!! It lasted us all day. If you have the choice of where to stay I think you will enjoy the Sheraton! We did!! 

Solution:
positive
