We had a stateroom on deck 3.
The window opens out to lower promenade deck, while it let in sunshine to tell us if it is day or night, and has a reflecting coating on the outside, the inside of the room was still visible at night, when it was dark out, had to close the blackout curtains.
Is it a very comfortable room, with a small sofa, writing desk and chair. Lots of amenities: hair dryer 230v charging point, very bright with many ceiling and wall lights. Always kept clean by the room attendant who visited the room more than twice a day to clear up.
Lovely beach, lots of eateries, shopping, activity.
