You guys have any idea how to get to Ace water spa?

Their address is:
399 Del Monte Avenue (near cor. Banaue St.)
SFDM, Quezon City

Im from the south...I can only manage to get myself to espaņa via nagtahan.
Can you guys show me hassle-free way to get there starting from espana? Im really not familiar with the places in QC.
I hope Im not asking too much... but can you please direct how to get back as well? heheh thanks guys!
