We have been quoted 15 euros a square

We have been quoted 15 euros a square meter to lay tiles, is this a fair price?  Had a couple of quotes but both were the same price, we are in a small town and not sure if I should get another quote from a larger company in large town near by.  Just would like to know what the average price is?   Also laying wall tiles in a bathroom the same cost of laying floor tiles as I asked one company who said they would charge 18euros a square meter for the walls.  Thanks for any help!
