Batangas City — The city, not the whole province
Choose the part of the city first. If you discuss the basilica surroundings, respect worshippers and arrange the conversation in an appropriate public place nearby.
Batangas City: Say what you mean by Batangas
An MTC profile that says Batangas may not mean Batangas City. Ask about the broad area before planning around Plaza Mabini or Kumintang Ibaba; you do not need someone's address to find out whether the journey is sensible. Being clear about the city saves a promising conversation from turning into a travel misunderstanding, especially when one person is reading from elsewhere.
