My stay in Sarmiento was perfect. It had everything I needed and my host Hernan provided me everything that I needed. He is responsive and always willing to help, and will go the extra mile for you. The location is literally a few minutes walk to the city core, public transportation, restaurants, bars, cafes and etc. There is a Dia (supermarket) right in front of the apartment and that was a BIG bonus for me.
I had a great stay at this location and will definitely come back. Hernan does not overpromise and under deliver.
