We stayed in 6175, which is a handicapped aft suite. It was a wonderful room, with more room than the three of us needed. I have never seen so much storage! It was nicely appointed with excellent craftsmanship (I'm a woodworker, so I notice such things). The bed was excellent. The window was quite big with a wonderful desk in front of it and sash big enough to sit in.
The balcony was very large with a table, 5 chairs and a chaise lounge. Previous reviews I'd read had warned that there is virtually no overhang over the balconies on deck 6 aft and that proved to be a handicap on the few times it rained during the cruise. I would have loved to have had the corner suite next door so I could have seen "around the corner" on the wrap-around balcony, but the very nice folk that stayed in it had booked before I.
