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

Input: Consider Input: When I was asked to stay at the Swissotel in Chicago, I immediately went to their website to check them out. What I found there was decent, nothing really stood out. It wasn't until I actually went there that my eyes were opened. The amazing customer service I received there was exceptional. Every whim and detail I asked for they helped me perfectly. The room was neatly fixed when I arrived and was cleaned every day. When I asked about more towels, the maids were happy to help me out. If I were ever to be in that area again, I know exactly where I'm staying, the Swissotel.

Output: positive

Input: Consider Input: Hyatt Regency Chicago seemed like a nice place to stay, but we didn't like it very much. The renovations were cheap and poorly done (our bathroom faucet was leaky and the carpet had bumps in it.) The staff was RUDE! I was trying to find a good cab service, and the guy behind the front desk made me wait for 20 minutes while he was finishing a phone call! Couldn't he have at least called someone else to help me? The "Babies Travel Lite" gave us the wrong sized diapers, so we had to go find some anyway, and with the hotel being located in the heart of the city that meant we found some unsavory characters along the way.

Output: negative

Input: Consider Input: The Hyatt Regency Chicago is a wonderful hotel. :) Me and my husband recently stayed there on a summer vacation, and it couldn't have been better! The staff was very polite and helpful, and the rooms were very clean, and they had some of the best beds I've ever slept on! Not to mention the view was amazing! If I had to rate this hotel I'd definitely give it five star, next time I'm in town I will most definitely stay there again!
Output: positive
