We were limited to only one full day in Terceira, and we were looking for a full tour of the island. Some options were cheaper, but this one had some amazing review and we just decided to tried it, and it worth every cent.
While travelling, I often feel difficult when you spend only a week or two to connect with local , to get their perspective on their day to day life, but during this tour, I feel we learnt a lot and I hope that I will find similar experience in my future travel.
Also, the communication was quite easy in English, which sometimes is tougher to me as a French Canadian when English is also second language.
