Santiago's apartment is exactly as it appears in the pictures. It's very comfortable and cozy with great views of the city. It's located in an awesome area in Palermo - close to a ton of cafes and restaurants and a quick walk to the metro station.
Santiago was very accommodating. Our flight arrived late at night and he made sure we were able to get checked in with the doorman. His guide for the city has a bunch of great suggestions as well. He was always able to quickly respond to any questions we had and checked in to make sure we were doing okay. I'd definitely recommend this place to anyone wanting to have an authentic Buenos Aires experience!
