Santiago (and Sebastian) were the most gracious hosts. Though my Spanish is minimal (and rusty for not having spoken since high school) both were patient, understanding and made me feel welcome. Their warmth shone through despite the sometimes barriers and I left feeling like I had two new friends :)
La Latina is a g-r-e-a-t home base from which to explore the city, and their place is right by the metro station. That said, you can also walk to all of the main sights from there in no more than a half hour. Highly recommend if traveling solo or with a buddy!
