the Sea is not rickety or falling apart, she is older, not particularly glamous and the cabins are small with no balconies. To off set this the crew is the best I have seen for friendliness, there are 2 pools, very unusual for a ship her size, the food is good the entertainment outstanding. What you get from a cruise in my opinion is up to you. The most important thing to remember is every ship is different and everyone has its own personality. If the itinerary and price is what you want "Go for it".
