I can't believe I was on the same ship as some of the people who have posted reviews below.
The Louis Aura is not the ship for you if you want a large, modern, facility-filled ship. Its a small, old, ship, but what it lacks in pizazz and facilities it more than makes up for in atmosphere and friendliness. To enjoy a cruise on this ship one must think of it as a small, comfortable but plain Greek hotel that happens to hop from island to island
First off, for a 45-year old ship I found it to be in remarkably good condition. Everything was clean and well maintained. The public rooms don't have much in the way of Wow and Bling, but they look modern enough and there is some very nice original Mediterranean art on display. A previous reviewer must have looked long and hard to find that ripped lounge chair because I certainly never saw one. I especially liked the lounge on the top deck of the ship which is partially open-air. It is a great place to enjoy the view and the sea breeze.
Cabins are small and do lack storage space but they are adequate enough for seven days. Mine was spotlessly clean and well looked after.
Some others here have complained about the food but I found it absolutely wonderful. It was prepared with fresh ingredients and tasted better than the food I have eaten on quite a few other ships that have more superior ratings. The cuisine is Greek, which means that there won't be a lot of beef on offer, but most cardiologists will tell you that that is not necessarily a bad thing. Other meats offered - lamb, pork chicken, fish - were excellent and so were the numerous Greek specialties offered.
Service from the predominantly Mediterranean and Eastern European crew was very good. The style is European which means the crew are more reserved than they are on US-based "Have a nice day" ships. That doesn't mean that they are not professional, pleasant and efficient. They won't be telling you their life stories though, and to be honest I much prefer that. I am on holiday to relax and I don't want to hear tales of how tough life is in Manila, Mumbai and Maracaibo.
The Greek Islands were absolutely stunning and the small size of the Louis Aura meant that it could dock at most of the ports and passengers were able to get on and off very quickly which allowed for maximum time ashore.
To sum up, the Louis Aura is a simple, comfortable, well run ship. It harks back to the more innocent era of cruising, before it all became so corporate and impersonal. Forget the large mega-cruise ships, go with an open mind, and you'll have a wonderful time.
I have sailed on a total of 38 ships - big ships, small ships, old ships, modern ships and everything in between. I would have no hesiattion recommending this ship.
