Smoking only
If you don't mind sleeping in a smoking room, then go ahead and call. Otherwise, don't even try it!!
When I tried to make a reservation on the phone, the lady told me not to make one but just to come in and she was sure that she would have one. (But when I asked for non-smoking, she said that she didn't have that.) I won't let my 3-month-old baby stay in an ash tray.
