My friend Rebecca and I were very grateful to be able to stay in Santiago's penthouse apartment. A very safe and secure building and neighbourhood, it was very nice to experience "porteño" life by staying in a fully equipped apartment as opposed to a hotel room. The apartment is perfectly located in Palermo Alto - only two blocks from the Subte (train/metro) and Santi was kind enough to give us a Sube card so we could start travelling on the Subte immediately! If your destination isn't easily accessibly via the Subte, there are also buses nearby, not to mention taxis are very cheap in Buenos Aires (at least compared to Australia!) Would stay again - highly recommended!
