Input: My wife and I stayed here for a long weekend and it was great. The check-in staff changed our room to a single bed without question, and the bar served the best martini I have had in a while. The rooms were well decorated and spacious, although it did get a little tight through the bathroom door. The bell staff was very accomodating and walked my wife up to our room when she arrived late. I would definitely stay here again!

Output:
positive
