6144 is a very nice Concierge Class Room. It is not wider than the average concierge class. The diagram fools you into believing that it is wider but the fact is that the diagrams does not show a corridor next to the room that goes between cabins which is used as storage space. That corridor even has a balcony. Technicaly you can open a door from the balcony of 6144 to the corridor's balcony for some extra space; which we did. The fresh flowers were dead by day 3 and not replaced. The evening h'orderves were nothing extraordinary. The balcony is longer as are the ones for suites 6145 & 6146, etc. Bottom line, I liked the room and if you are shooting for concierge class it is probably your best choice along with the 6135 & 6136.
