On approach FO lowered landing gear; got 'L/G Not Down/Locked' ECAM. Followed ECAM which had us cycle the gear. No help; ECAM then directs to lower gear manually (gravity). Gear then showed down.  Landed; had to stop on runway due to no nose wheel steering. Got towed off runway to gate.
[I] recycled the landing gear lever per the ECAM and the landing gear failed to extend normally. Continuing with the ECAM; I used the Gravity Extension Handle; turned the handle 3 times; and the landing gear extended; gear doors remained open and nose wheel steering was Amber on the display. F/O opened the QRC; and referenced all the cleanup items. The crew discussed considerations on landing; stopping straight ahead and getting a tug to the gate.
A320 flight crew reported using the alternate landing gear extension procedure when the gear failed to extend on approach.
