Yoyogi YHA

Hey guys, its time for me to head back to Japan for a few days!
My friend flys in the same time as me, and we are looking at staying at Yoyogi YHA (shinjuku side), has anyone stayed here? Or can anybody recommend an even cheaper or better option.
On a tight budget as per usual!
Also what is the best, cheapest way to get to Shinjuku from Nariita airport?
Looking forward to reading any helpful info, thanks in advance.
Oh yeah, I dont have a YHA card either, so if its going to be cheaper to stay somewhere else (in that general vicinity) without paying the 2500yen each for a card, then we may as well do that.... yeah I guess this doesnt make much sense...

A cheap inn of Tokyo

Sorry for the late reply, but thankyou very much Hiroyuki san!

i love the building + location but management ichirochi yukio what her name is eh
they have $5 dollar breakfast gym with pool
i was such a bad foreign person in this place
nothing else in shibuya shinjuku yoyogi harajuku area is can touch it - i done tried for three solid years!
it is the number one place to stay in tokyo imo -- that is why i am so mad i cannot stay without using ibtl or what they name and credit card info :<
30 dollars to be in the mix with NO CURFEW -- $30 hotels in japan ALL have curfew -- the ones that will allow foreign peoples anyway
check itcj website just in case?
