I found a lot on Amazon but I’m from France so I can’t check them up.

I would like a tiny travel guide which includes maps, bus lines, car rental, and many tips (not really fancy restaurants & hotels) and, if possible, some information on Olympia.

Thanks for you help, sorry for my english.
Thank you for your answers and these really good websites.

However I’m looking for a paper guide (book size) to carry out wich includes maps and bus lines. Any idea ?
