Lunar landing is harder in many ways than a Martian landing. Without an atmosphere, you cannot aerobrake.

That's a coin with a flipside though: you also don't need much in terms of heatshields so in that sense it is easier than on Mars.
A Mars landing needs both heatshields (because it does have an atmosphere) and retro-rockets to land with (because that atmosphere is not so dense that you can use it for gliding).
