Very close to the metro, not even a two minute walk. The apartment was beautiful and Angel was so incredibly nice.
We met him and he jumped in the car to direct us to the parking garage which is maybe a 5 minute walk. We walked back to the airbnb and though we hardly speak any Spanish, and he didn't speak English, he pointed out areas of interest in the neighborhood.
The area is super close to the center of the city by metro, very easy to get around. The only thing that bothered us was there was a bar downstairs and the patrons were so loud, some nights they would go until 5:30 in the morning.
