Sergio is very kind, someone you can trust. Any question you have about the city, he will know the answer, his partner even made dinner for me, a local food. Room is very big, has A/C, TV, queen (or king?), you can even use the washing machine. Good location, you have a mini market next to this house to buy anything you need and very close to the subway. A great place to stay and you have someone who has always lived in Buenos Aires to help you.
