Eduardo ( i think that was his name) was really relaxed, easy to chat to and sweet. He showed us around a lot of alternative arts, street art and cool places that we would never have known about without the tour. Definitely worth the money, from 2 art enthusiasts from the UK.
We did not consider enough about dressing for the cold weather. There were warmer moments, on the trams and in a cafe, but being outdoors for 3-4 hours ( in early March) does get really cold, this was not the tour guide’s fault, but I should have worn warmer shoes and more layers!
