The location of this hotel is great, and the staff was friendly. However, during our stay the fire alarms went off 2 times. The first time we walked down all 18 flights of stairs only to be told that there was no emergency and that we could go back to our room. The next time it went off at 2 am. We once again started down the stairs only to hear again that it was a false alarm. Why did it keep going off? Also this is out of their control, but the protestors at the nearby hotels were pretty disruptive. We could hear them from 7 am-10 pm every day. We couldn't sleep in and thought it was pretty disruptive. It would have been nice to have been told in advance about this.
