This question already has an answer here:

Trying to remember title (and even most content!) of following story:

Something along the lines of a gigantic abandoned spaceship drifting through the galaxy for over a galactic turn, humans had colonised it and run it, and trade passage on the spaceship with other races in return for technology/goods. Think the main plot was over an attempted take over of the ship by another race.

Apologies for vagueness.

    Hi - is there any other information you can provide? For example, when you read it, the approximate age of the book, U.S., British, other..? Was it a book? Story in a magazine? Do you recall any artwork? – Tim Jan 10 '17 at 20:01
  • This is so vague, it could even be Rama. – Mr Lister Jan 10 '17 at 21:12

That's probably the Great Ship series by Robert Reed, of which the first entry is the novel Marrow.

When a jovian sized, artificially-created structure enters the galaxy, a society of technologically advanced humans (capable of interstellar flight and functionally immortal) are the first to intercept and investigate it. Finding it to be an intergalactic ship, they decide to convert it into a cruise ship, inviting alien races to join them in its massive, uncharted interior as it makes a slow circumnavigation of the Milky Way.

    Woops, looks like you beat me by a few seconds. I'll delete mine but just point out that, if it is indeed this book, it's also the answer to scifi.stackexchange.com/q/1030/65768 – starpilotsix Jan 10 '17 at 20:07
  • It was the Marrow book - thanks for much for the reminder! – Meles Jan 20 '17 at 14:02
