this hotel is not up to Sheraton standards. The walls are thin, you can hear everything in the hallways. they are currently renovating hallways which look terrible. rooms are updated. BUT worst of all the hotel is next to train tracks , and the train horns blast at all times during the night, one day starting at 4 am and the second from midnight onwards. Staff were gracious. They moved my room to a "quieter area" , which made absolutely no difference . I had to leave and get a different hotel to get any sleep at all. They charged me for 3 nights even though I had complained on the first day and told them I needed to leave.
