I visited my cousins room who were here on vacation, first time to the USA. The concierge was helpful in teaching us how to use the hotel WiFi. The furniture in the hotel rooms were not in great condition, just working condition. We had also noticed that after housekeeping made the bed and cleaned the room, the was some sort of strain on the duvet cover, possible a blood strain or something else. That was unacceptable as my cousins said that was not there; however, housekeeping respond promptly and we appreciated their response.
