PROBLEM: Review: I was here on business so I needed to get some rest the next day but the walls were so thin that I could here all the carrying on in the neighbors room till 3 am. This was very beautiful building the room was a lot smaller than I expected and the staff were not very friendly. The person at the front desk had no personality, did not even welcome me to the hotel. All in all I don't think I will be back.
Polarity: Negative

SOLUTION: true

PROBLEM: Review: I loved this hotel - reasonable for downtown Chicago, an older hotel with a great reno (a bit over-the-top design, but still very lovely and charming), clean rooms, and very friendly staff. They're also amazingly pet-friendly - they welcomed our 130lb Mastiff cross with a gift bag (treats and directions to an off-leash area), and even had a cute blackboard with visiting dog's names on it.
Polarity: Negative

SOLUTION: false

PROBLEM: Review: Located right in the heart of downtown Chicago i visited this hotel on a business trip. The first things i noticed was how friendly the staff is, and how clean the rooms are (even compared to other luxury hotels) seeing as i had a night layover before my meeting i decided to stop by the Terrace and get a drink, i got a mojito and i must say i was very impressed, i've had my share of mojitos and it was one of the better ones, once i retired back to my room i found the sound system to be excellent, bed was soft and the TV didn't appear burned out at all. Overall i give this a five out of five, the staff was helpful and friendly the whole time and the atmosphere was perfect, i wish i could have stayed longer.
Polarity: Positive

SOLUTION:
true
