Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

Let me give you an example: I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.
The answer to this example can be: positive
Here is why: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

OK. solve this:
I booked this hotel with great expectations. I had family visiting from outside the country and wanted them to have a good experience in Chicago. Upon arriving to the hotel (at the exact time I indicated in my reservation) I was told I've been "downgraded" to a lesser quality room. I travel very often and never had this before. Moreover, I did not hear a single "I'm sorry", it was like usual business. What bothered me the most was that the receptionist kept telling me "I will decrease the rate for you" "what do you think, nice eh?" like he was doing me a favor!!!! They decreased the rate to that of the rooms they gave us of course (which is the legal thing to do, since I am sure is illegal to charge me for one room and give me a lesser value one for the same money). They did not care that I wanted higher level room independent of value. I did not know what to say, since this never happened to me before, also with family present did not want to start arguing. The rooms were nice (not as nice as I thought) and location is good, however be aware that they might not honor your reservation and not even apologize for this. That is enough for me not to go back again.

Answer:
negative
