A lot of information + new spots in Madrid!!
The experience was really great, way better than I expected. I asked Sergio to take me in a "kind-of historic" tour and that's definitely what he did! He explained a looot of facts and curious info about all the places we visited, which many if them I didn't know. I got to see a totally different side from Madrid and we ended up eating tapas in a very local and popular bar in Alcalá street, one of he most well-known. Overall, I'd 100% repeat the experience! :)
