My review will be controversial with other reviewers and I have been thinking for a few days to write this publicity or not. But I decided to let people make their own evaluation. I was so disappointed with the tour because of the guide was very rude to me. This begin when I first met him in the meeting point and tried to be friendly by greeting him saying hola. But just because I sounded more Spanish to him than Portuguese, he didn't respond to my greeting at all, but directly asked "what's your booking name" with an angry intonation. I was wondering why he acted rudely but I was thinking maybe this is just an issue with different personality/culture. Then a minute after he got my name and my friend name on his list and we were about to leave him to find a space to wait for others, he suddenly said something that made me understand why he has that angry intonation before. He said " can I teach you something! Never said hola to Portuguese people because it's Spanish.....and he said how to pronounced "Olá" This is all sounds so small thing, but if you were there and heard how he spoke to me, his intonation, and his body language - you will quickly can understand that this is not a small thing - this is someone who got annoyed by a young foreigner who has no idea about the real tension between the two countries and treated her disrespectfully. I am happy if someone teach me about their local language or correct my pronunciation - but at that day, that wasn't his intention. He knows exactly how angry he was just because my greeting sounds Spanish rather than perfect Portuguese greeting, and that was in Porto, not Spain.
