do all rooms on the 4th floor have a terrace to use? i booked the ganesvroot suite.
I'm not sure about all of the rooms - call the hotel
All the suites are different, depends on view, dice of the balcony and availability by the time you arrive. You can always call them and tell them exactly what you are expecting and see if they reserve you in advance what you want.
