That description fits a standard room in both the Mansions of Magnolia Bend, and the Alligator Bayou buildings.
Depending on the size of your party, and room availability, you could be in Alligator Bayou. You will notice it states that some of the rooms have the trundle bed, but that is outdated, because during the recent refurb, the trundles were replaced with murphy beds.There are some preferred rooms in Alligator Bayou, and some in Magnolia Bend. All the royal rooms are in Magnolia Bend, in Oak Manor,and Partierre Place.
Several AB buildings, such as 14, and 18 are preffered buildings.
If you want to be in the mansions, you can always ask at check in.
