Where to book?

Hello! im planning to go to taiwan next year, May. Saan po bang app/website maganda magbook ng hotel? I saw some peeps na nagsasabi panget sa agoda or booking and mag direct nalang daw sa hotel. If that’s the best option, how po macocontact ung mismong hotel? whenever I click website of some hotel kasi napupunta rin sa booking owlting which i guess is sa bookingdotcom din? any advice? thank youuu!
